i need each and every step with proper explanation

(a) (b) (c) (d) A negative charge Q 1s uniformly distributed throughout a solid insulating sphere with radius a. It 1s surrounded by a thick conducting spherical shell with mner radius b and outer radius c. The shell carries a net charge of + Q. (10 points) Find charges on the inner and outer surfaces of the conducting shell. (10 points) Find the magnitude and direction of the electric field E(r) with |r| c. (5 points) Find the electric potential V(r, [r| = c) just outside the conducting shell referenced to infinity. (10 points) Find the electric potential V(r) at the center of the solid sphere referenced to infinity. - T
