A solid conducting sphere of 10 cm radius has a net charge of 40 nC. If the potential at infinity is taken as zero, what is the potential at the center of the sphere?

Question

The potential inside a conducting sphere is the same as on its surface. The potential V at the surface of a sphere with charge Q and radius r is given by V = kQ/r, where k is Coulomb's constant. Substituting the given values, V = (9 x 10^9 Nm²/C²)(40 x 10^-9 C)/(0.1 m) = 3.6 x 10^3 V.
