Homework Help: Electric fields and spheres

  1. Jan 31, 2012 #1
    1. The problem statement, all variables and given/known data
    A total charge Q is spread uniformly over the surface of one hemisphere of a hollow insulating spherical hull of radius R. The magnitude of the electric field at the centre of the ball(point C) will be?

    3. The attempt at a solution

    The answer was less then that KeQ/R^2, was this because the electric field on the shell radiates uniform-illy outward and inward but and the centre, some of the electric field cancels at point c??
