A solid metal ball with a radius of 30 cm has a net charge of 77 nC.If the electric potential is zero far away from the ball,what is the electric potential at the center of the ball?

Question

Quizplus · Accepted Answer

The electric potential at the center of a charged sphere is given by V = kQ/R, where k is Coulomb's constant, Q is the net charge on the sphere, and R is the radius of the sphere. Plugging in the given values, we get V = [(9 x 10^9) x (77 x 10^-9)] / (0.3) = 2300 V. Therefore, the best choice is C.
