Practice: Electric Potential and Potential Energy of an Insulating Sphere
Consider a solid, insulating sphere of radius and uniform charge density .
a) Find the electric potential V of the sphere (both inside and outside).
b) Plot your results as a function of in addition to the plot of the conducting case. To make plotting easier, you can set all constants equal to 1 (Q, , , R).
c) Find the electric potential energy U for the insulating sphere.
