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

Question 2

Two large parallel conducting plates are 8.0 cm apart and carry equal but opposite charges on their facing surfaces. The magnitude of the surface charge density on either of the facing surfaces is 2.0 nC/m2 . Determine the magnitude of the electric potential difference between the plates.
 a. 36 V
  b. 27 V
  c. 18 V
  d. 45 V
  e. 16 V
