Hi friends, here it is given two conducting seats.
00:07
One is at y -skel -to -0 and another at y -skel to 2 -centimeter.
00:29
This is positively charged.
00:33
This is negatively charged.
00:34
Having surface charge density plus 4 .5 nanoculum minus 4 .5 nanoculum.
00:43
We have to find feel intensity at we have to find a field intensity.
00:54
Electric field intensity at y is equal to one centimeter y is equal to three centimeter and y is equal to minus one centimeter so suppose this is the point a at point a field intensity will be e a1 and ea2.
01:36
So at a it will be hea1 plus ea2 that is sigma upon 2 epsilon not plus sigma upon 2 epsilon not sigma is given 4 .5 into 10 to the power minus 9 8 .85 10 to the power minus 12 so fail intensity will be 508 .5 newton percola directed from positive plate to negative plate.
02:17
Now this is the point b.
02:20
At b electric field will be ev1 and ev2.
02:28
So net electric field at b point at y is equal to 3 centimeter, ev1 minus ev2...
