A non conducting sphere of radius ′a′ has a type charge ′+q′ uniformly distributed throughout in volume. A hollow spherical conductor having inner and outer, radii ′b′ and ′c′ and net charge ′−q′ is concentric with the sphere (see the figure)
Read the following statements
(i) The electric field at a distance r from the center of the sphere =14πε0qra3 for r<a.
(ii) The electric field at distance r from the center of the sphere for a<r<b=0
(iii) The electric field at distance r from the center of the sphere for b<r<c<=0
(iv) The charge on the inner surface of the hollow sphere =−q
(v) The charge on the outer surface of the hollow sphere =+q.
