Question

A charge is located at the center of sphere A (radius RA = 0.0010 m), which is in the center of sphere B (radius RB = 0.0012 m). Spheres A and B are both equipotential surfaces. What is the ratio VA/VB of the potentials of these surfaces?

Answer 1

The ratio of the potentials is 1.

Step-by-step explanation:

The ratio of the potentials is given by the inverse ratio of the radii. Since sphere A is at the center of sphere B, the potential at the center of sphere B is equal to the potential of the center of sphere A. Therefore, VA = VB. So the ratio VA/VB is 1.
