A uniformly charged spherical shell with surface charge density omega contains a circular hole in its surface. The radis of the hole is smalle compared with the radius of the sphere. What is the electric field at the center of the whole(Hint: the field within the whole is the suprposition of the field due to the original uncut sphere, plus the field due to a sphere the size of the hole with a uniform negative charge density -omega)
I don't undestand this because the electric field, if the sphere were solid, doesn't depend on the radius, it's just q/(epsilon_0). Any idea how this works out?
