Electric field and potential.

[varunsarda88]

Can anyone please help me out...
what is the electric field and potential of a uniformly charged sphere...both inside and outside...
also the same for hollow sphere..
pleasez

You really must show SOME work, its the rules of the forums.

To get you started...

HINT: Spheres have the same symmetry a POINT charges. What are the formulas and laws you can use to find Fields and Potentials?
For inside the sphere, think GAUSS'S LAW.

for field it is k*charge/distance^2 and potential is k*charge/distance
where k is a constant
