We are given A solid non-conducting sphere of radius R It carries a uniform volume charge density We are to find the ratio of electric field at r R on surface to that at r R2 inside Electric Field due to a uniformly charged solid sphere For a sphere with uniform volume charge density , the electric field depends on distance r from the center A Outside or at surface r R The electric field at the surface is twice that at r R2 .
