Question

A solid spherical ball of radius 4 meters has a charge of 8 nC.

a) Calculate the electric potential at r = 2, r = 4, and r = 6 meters away from the center of the ball if it is a conducting sphere.

b) Calculate the same things if it is an insulating sphere of uniform charge density.

c) Calculate the same things if it is an insulating sphere of non-uniform charge density, ρ = kr²

^{Answers should be:}

a) V2 = 18 volts, V4 = 18 volts, V6 = 12 volts

b) V2 = 24.75 volts, V4 = 18 volts, V6 = 12 volts

c) V2 = 22.22 volts, V4 = 18 volts, V6 = 12 volts
