00:00:00.940 --> 00:00:05.589 A:middle L:90%
Hello. Strings like tired or discussion? Electrostatic force
2
00:00:06.370 --> 00:00:09.849 A:middle L:90%
. Okay, No. Suppose you have the condition
3
00:00:09.990 --> 00:00:13.810 A:middle L:90%
in Rich State, A straight line and a charge
4
00:00:13.810 --> 00:00:17.609 A:middle L:90%
off. Six Micro Coolum is placed at the position
5
00:00:17.609 --> 00:00:22.379 A:middle L:90%
. One positive charge and at position to a charge
6
00:00:22.379 --> 00:00:26.570 A:middle L:90%
of 1.5 Micro cooler. Misplaced. No. Okay
7
00:00:26.870 --> 00:00:32.479 A:middle L:90%
. And at Position three, a charge off minus
8
00:00:32.479 --> 00:00:36.469 A:middle L:90%
two. Micro Kula misplaced. Okay, Now you
9
00:00:36.469 --> 00:00:40.369 A:middle L:90%
have to find out the force on each charges.
10
00:00:40.689 --> 00:00:43.500 A:middle L:90%
That is total force on one total force onto and
11
00:00:43.500 --> 00:00:47.539 A:middle L:90%
total four soul. I'll see the charge. Q
12
00:00:47.539 --> 00:00:53.200 A:middle L:90%
one is six micro Coolum that is six into 10
13
00:00:53.200 --> 00:00:56.509 A:middle L:90%
. Rest part minus six Coolum. Similarly cuter is
14
00:00:56.509 --> 00:01:00.969 A:middle L:90%
1.5 micro column That is 1.5 into 10 days by
15
00:01:00.969 --> 00:01:06.329 A:middle L:90%
minus six Coolum and Coo tree is minus two Micro
16
00:01:06.329 --> 00:01:10.969 A:middle L:90%
Coolum that is minus two into tenders by minus six
17
00:01:10.980 --> 00:01:14.439 A:middle L:90%
. Good. Okay. And the distance between them
18
00:01:14.450 --> 00:01:19.030 A:middle L:90%
is three centimeter from one toe and it just two
19
00:01:19.030 --> 00:01:25.340 A:middle L:90%
centimeter from photo three. It means that our want
20
00:01:25.349 --> 00:01:30.090 A:middle L:90%
to is a three centimeter. That is, Joe
21
00:01:30.099 --> 00:01:36.730 A:middle L:90%
went 03 centimeter and our duty is so sanctimony.
22
00:01:36.730 --> 00:01:38.510 A:middle L:90%
Inter, that is judo point. You don't use
23
00:01:38.510 --> 00:01:49.189 A:middle L:90%
a meter off meter. Uh uh, 13 that
24
00:01:49.189 --> 00:01:55.650 A:middle L:90%
is five centimeter means 0.5 05 centimeters. Europe When
25
00:01:55.650 --> 00:01:57.319 A:middle L:90%
Joe five meter. I am writing all the values
26
00:01:57.319 --> 00:02:00.709 A:middle L:90%
here so that you can easily put these values in
27
00:02:00.900 --> 00:02:06.819 A:middle L:90%
, Uh, in our example when we're okay.
28
00:02:06.849 --> 00:02:09.680 A:middle L:90%
Lets just find the net force on one basically on
29
00:02:09.689 --> 00:02:14.490 A:middle L:90%
one in the force on one do toe to Isn't
30
00:02:14.490 --> 00:02:16.930 A:middle L:90%
this direction that is f one toe? Okay.
31
00:02:17.080 --> 00:02:21.509 A:middle L:90%
And the fourth on one due to three will be
32
00:02:21.740 --> 00:02:25.860 A:middle L:90%
in this direction on the neck forces af one that
33
00:02:25.860 --> 00:02:29.860 A:middle L:90%
we have to find out these. Okay, here
34
00:02:29.860 --> 00:02:32.960 A:middle L:90%
we are taking in vector notation that direction, it
35
00:02:32.960 --> 00:02:37.930 A:middle L:90%
means that have formed factor will be I'm assuming right
36
00:02:37.930 --> 00:02:40.400 A:middle L:90%
side to be positive. OK, so have one
37
00:02:40.400 --> 00:02:46.469 A:middle L:90%
toe negative plus half one three vector positive because this
38
00:02:46.469 --> 00:02:51.139 A:middle L:90%
is the negative charge it will attract this six Michael
39
00:02:51.360 --> 00:02:54.430 A:middle L:90%
will charge towards herself and 1.5 Coolum is a positive
40
00:02:54.430 --> 00:02:58.259 A:middle L:90%
charge. It will rebel this six micro cooler.
41
00:02:58.569 --> 00:03:00.860 A:middle L:90%
Okay, So simply if you put the values than
42
00:03:00.870 --> 00:03:07.270 A:middle L:90%
it will be que q one que to buy our
43
00:03:07.270 --> 00:03:15.250 A:middle L:90%
want to square plus Okay, Q one que three
44
00:03:16.610 --> 00:03:23.219 A:middle L:90%
a phone are 13 square. Okay, The value
45
00:03:23.219 --> 00:03:25.080 A:middle L:90%
of case Constand Index Value s case, it goes
46
00:03:25.080 --> 00:03:28.469 A:middle L:90%
to 19 to 10. This partner. Now,
47
00:03:28.469 --> 00:03:30.129 A:middle L:90%
if you put the whole the values here, then
48
00:03:30.129 --> 00:03:35.340 A:middle L:90%
you will get minus 90 Newton. And from here
49
00:03:35.340 --> 00:03:36.939 A:middle L:90%
, if you put the values off Q one Q
50
00:03:36.939 --> 00:03:38.699 A:middle L:90%
three and are 13 you will get the value.
51
00:03:39.139 --> 00:03:46.159 A:middle L:90%
43 points do Newton. So the net So the
52
00:03:46.159 --> 00:03:53.590 A:middle L:90%
net force on one is minus 46.8 newton. That
53
00:03:53.590 --> 00:03:55.219 A:middle L:90%
is in the left side. AF one, this
54
00:03:55.219 --> 00:03:59.789 A:middle L:90%
is the net. Force the net Need certain forces
55
00:03:59.789 --> 00:04:01.150 A:middle L:90%
in left side because the minus sign is come.
56
00:04:01.639 --> 00:04:06.430 A:middle L:90%
Okay. No, we have to find the force
57
00:04:06.430 --> 00:04:12.599 A:middle L:90%
on charge too. That is after. So the
58
00:04:12.599 --> 00:04:16.160 A:middle L:90%
force in charge to is have to due to one
59
00:04:16.269 --> 00:04:18.959 A:middle L:90%
force in charge to do 21 and it is after
60
00:04:18.959 --> 00:04:23.480 A:middle L:90%
one and force on charged to do 23 after three
61
00:04:23.790 --> 00:04:28.050 A:middle L:90%
. Now you can see that from hair. Ah
62
00:04:28.629 --> 00:04:30.689 A:middle L:90%
, the from here. This is three and this
63
00:04:30.689 --> 00:04:38.740 A:middle L:90%
is 11.56 and minus two after one is in this
64
00:04:38.740 --> 00:04:40.829 A:middle L:90%
direction. Okay, that is four from 2 to
65
00:04:40.829 --> 00:04:44.129 A:middle L:90%
1. And also after 31 is also in this
66
00:04:44.129 --> 00:04:46.310 A:middle L:90%
direction because this is negative charge. It will attract
67
00:04:46.310 --> 00:04:47.589 A:middle L:90%
this. So the net force, no doubt Lee
68
00:04:47.589 --> 00:04:50.160 A:middle L:90%
comes in this direction means right side. That is
69
00:04:50.160 --> 00:04:55.660 A:middle L:90%
after. So this will be a k q to
70
00:04:55.670 --> 00:05:02.689 A:middle L:90%
Q one by are 12 square plus que que took
71
00:05:02.689 --> 00:05:09.389 A:middle L:90%
you tree by our trees square I wrote the older
72
00:05:09.389 --> 00:05:12.750 A:middle L:90%
values in the stichting. So if you put all
73
00:05:12.750 --> 00:05:18.850 A:middle L:90%
the values you really get here 19 Children and here
74
00:05:18.850 --> 00:05:24.629 A:middle L:90%
you will get 67.5 Newton and the torta force on
75
00:05:24.629 --> 00:05:32.550 A:middle L:90%
afterwards 1 57.5 Newton in the right side. Okay
76
00:05:33.339 --> 00:05:39.079 A:middle L:90%
, No, let us find the force 13 basically
77
00:05:39.079 --> 00:05:44.860 A:middle L:90%
force on 31 toe tree minus 21.5 and six.
78
00:05:44.870 --> 00:05:47.870 A:middle L:90%
Okay, so forth. 24th on three due to
79
00:05:49.040 --> 00:05:53.180 A:middle L:90%
one is in this direction. Force on 32 to
80
00:05:53.180 --> 00:06:00.500 A:middle L:90%
1. And also force on trade due to two
81
00:06:00.509 --> 00:06:03.000 A:middle L:90%
is also in this direction. So no doubt little
82
00:06:03.000 --> 00:06:05.410 A:middle L:90%
red result and force comes in the left side.
83
00:06:05.410 --> 00:06:10.889 A:middle L:90%
That is after after. So after we will be
84
00:06:11.680 --> 00:06:18.149 A:middle L:90%
minus off at 31 minus after a pool. Okay
85
00:06:18.379 --> 00:06:25.389 A:middle L:90%
, so after even plus after+32 it will be
86
00:06:26.649 --> 00:06:30.879 A:middle L:90%
, um Okay, You three Q one a bone
87
00:06:30.889 --> 00:06:35.670 A:middle L:90%
R 13 square plus k. You took you tree
88
00:06:35.980 --> 00:06:41.139 A:middle L:90%
a bone r tree to square. Okay, Now
89
00:06:41.139 --> 00:06:43.389 A:middle L:90%
, if you put all the values you will get
90
00:06:45.329 --> 00:06:54.389 A:middle L:90%
43.2 from here and 67.5 Newton from here. Soak
91
00:06:54.620 --> 00:07:00.439 A:middle L:90%
the net. Force Will comes out to be 110.7
92
00:07:00.800 --> 00:07:03.089 A:middle L:90%
Newton in left side. This is the fourth country
93
00:07:03.430 --> 00:07:08.379 A:middle L:90%
. So we find that the force on various charges
94
00:07:08.519 --> 00:07:11.389 A:middle L:90%
actually, initially, this is our child system.
95
00:07:11.759 --> 00:07:14.610 A:middle L:90%
Okay, so we find the net. Force one
96
00:07:14.610 --> 00:07:15.750 A:middle L:90%
, Charge one that force in charge. Toe and
97
00:07:15.750 --> 00:07:18.610 A:middle L:90%
net. Force on charge three. Well, this
98
00:07:18.610 --> 00:07:20.720 A:middle L:90%
is all from me for this video. I hope
99
00:07:20.720 --> 00:07:23.350 A:middle L:90%
you will like the video. Thank you.
