A solid conducting sphere of radius a carries a net positive charge 2Q. A conducting spherical shell of inner radius b and outer radius c is concentric with the solid sphere and carries a net charge –Q. Let c > b > a.
a) Discuss the distribution of the charges.
b) Calculate the surface charge density on the three surfaces i. radius a ii. radius b iii. radius c.
c) Find the electric field in all the regions. Express this as a function of r measured from the center of the spheres
