Question

A small conducting ball that carries a charge of 30.0 nC is
located at the center of an electrically neutral hollow conducting
sphere of inner radius 100 mm and outer radius 150 mm. What
is the surface charge density (a) on the sphere’s inner surface and
(b) on its outer surface? (c) Determine the electric field as a function
of r, the radial distance from the center of the sphere

Baljit · Accepted Answer

Sphere is hollow and neutral initially that mean there is no charge on the surface of sphere and there is no electric field inside sphere.
Now when we induced +30nC charge ate the center of the sphere. It will induce -30nC charge on the inner surface of the sphere.
