Let's talk about this question were given that there's a uniformly charged, uniformly distributed over the volume, uniformly charged.
00:09
Uh in saluting sphere and the current is distributed over the volume and it has a radius of five cm in charge of four microgram.
00:18
You find a potential difference between the center of the sphere and the sofas of the sphere.
00:22
So this is all this fear looks like and the charges uniformly distributed.
00:26
Then there's a center which has a potential of a and the surface which has the potential of being.
00:32
So we'll find the potential difference between these two potential difference.
00:36
Uh definitely we got to find uh we got to find the value of uh the potential at each point.
00:46
So the potential at the center is given by is given by three kq three kq over two times r.
00:55
Where r is the radius of this particular is fear.
00:59
And the potential of potential or be or at the surface is given by kq over r where r is again the radius of the is fear.
01:07
So we need to find the potential difference between the center of the sphere and the surface of the sphere.
01:12
So we a minus we be, it's got to be equal to three kq over two ar minus cake...
