Three identical point charges (+2.0 nC) are placed at the corners of an equilateral triangle with sides of 2.0-m length. If the electric potential is taken to be zero at infinity, what is the potential at the midpoint of any one of the sides of the triangle?
 a. 16 V
  b. 10 V
  c. 70 V
  d. 46 V
  e. 44 V

Question 2

Four identical point charges (+6.0 nC) are placed at the corners of a rectangle which measures 6.0 m  8.0 m. If the electric potential is taken to be zero at infinity, what is the potential at the geometric center of this rectangle?
 a. 58 V
  b. 63 V
  c. 43 V
  d. 84 V
  e. 11 V
