Shown below are two concentric conducting spherical shells of radius Each of finite thickness much less than either radius. The inner and outer shell carries a net charge That is positive. What is the dielectric field for
a) r<R1
b)R1<r<R2.
c) r>R2.
d) What is the net charge on the inner surface of the inner shell, the outer surface of the inner shell and the outer surface of the outer shell.
