So let's start with the problem.
00:12
There are three identical metal spheres, okay? so just assume you don't look after the size, okay? just for your understanding, okay? these are the identical spheres.
00:25
This is a, this is b, and this is c, and the sphere a carries 5 q charge, b carries minus q, and c carries no net charge, so it will be zero.
00:37
Okay, so first first a and b are touched okay and they are separated and in second case c is touched with a and third case c is touched with b okay so what all we have to find is you have to find a charge on c and and the total charge on all of the spheres on a, b and c, when they are touched, okay? before they are allowed to touch and after they had touched, after they touch, okay? so yeah, let's start.
01:29
So the concept over here is i'll just write it down, okay, when two metal spheres.
01:36
Years are touched, okay, are touched, they will come to equal potential, okay? equal potential will be there.
01:57
Okay.
01:58
And when they are identical, identical in the sense that same radiance, okay, same radiance.
02:11
Same radiance, that is same radius...
