in the a solid insulating sphere, A, of radius R_A, is located at the origin with a net charge of Q_A distributed uniformly throught it. it is surrounded by a spherical conducting shell, B, of in radius R_B1>R_A and outer radius R_B2 > R_B1 which carries a net charge Q_B.

A) what is the total charge on the inner surface of B (at r= R_B1)?

B) what is the total charge on the outer surface of B ( at r= R_B2)?

C) what is the electric field for each origon (r<R_A, R_A <r<R_B1, R_B1 < r <R_B2, and r > R_B2)

D) sketch a graph of the electric field as a function of r.

note: for spherically symmetric distributions, dxdydz=4πr^2dr
