Q. 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.
