A solid conducting sphere (radius = 5.0 cm) has a charge of 0.25 nC distributed uniformly on its surface. If point A is located at the center of the sphere and point B is 15 cm from the center, what is the magnitude of the electric potential difference between these two points?
 a. 23 V
  b. 30 V
  c. 15 V
  d. 45 V
  e. 60 V

 a. 36 V
  b. 27 V
  c. 18 V
  d. 45 V
  e. 16 V
