A conducting sphere with an inner insulating sphere inside of it, carries a total charge of 5 nC. The charge within the inner insulating sphere is -5 nC and uniformly distributed over the volume of the inner insulating sphere.
a) What is the charge on the inner surface of the conducting shell?
b) What is the charge on the outer surface of the conducting shell?
c) Calculate the electric field everywhere for this system.
d) Sketch a plot of electric field as a function of radial distance for this system.
