In the figure a solid sphere of radius a=3.80cm is concentric with a spherical conducting shell of inner radius b=2.00a and outer
radius c=2.40a. The sphere has a net uniform charge q_(1)=+7.61fC; the shell has a net charge q_(2)=-q_(1). What is the magnitude of the
electric field at radial distances (a) r=0cm, (b) r=(a)/(2.00), (c) r=a, (d) r=1.50a, (e) r=2.30a, and (f) r=3.50a ? What is the net charge on
the (g) inner and ( h ) outer surface of the shell?
