    Can any one 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..

    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
