Identical 2.0-mC charges are located on the vertices of a square with sides that are 2.0 m in length. Determine the electric potential (relative to zero at infinity) at the center of the square.
 a. 38 kV
  b. 51 kV
  c. 76 kV
  d. 64 kV
  e. 13 kV

Question 2

Three charged particles are positioned in the xy plane: a 50-nC charge at y = 6 m on the y axis, a -80-nC charge at x = -4 m on the x axis, and a 70-nc charge at y = -6 m on the y axis. What is the electric potential (relative to a zero at infinity) at the point x = 8 m on the x axis?
 a. +81 V
  b. +48 V
  c. +5.8 V
  d. -72 V
  e. -18 V
