Two metal spheres are connected by a long wire with a switch. The radius of the larger sphere (B) is b= 0.20 m and the radius of the smaller sphere (A) is a= 0.080 m. Initially the switch is open and both spheres have zero charge. Then charge Q0 = 1.0 μC is placed on the larger sphere.
(a) Calculate the electrostatic potential at the surface of B.
(b) Calculate the total electrostatic potential energy.
(c) Now close the switch. The system of two spheres will come to a
new equilibrium. Calculate the equilibrium charge on the smaller sphere (A).
(d) Calculate the final electrostatic potential at the surface of the smaller sphere (A).
I already solved (a) by using V=k*q/r
I'm lost on the rest of the problem though.
