A plastic sphere with a radius of 4 cm is surrounded by a concentric metal shell of 7 cm inside radius, and 10 cm outside radius. The outer shell has a net charge of +5 Coulombs, while the plastic sphere inside has a uniformly distributed charge of -10 Coulombs.

What is the electric potential relative to infinity at a distance 15 [cm] from the center of the plastic sphere i.e. outside the conducting shell, and why?

2b. What net charge resides on the inner surface of the conducting shell, and why?
