Point charges of equal magnitudes (25 nC) and opposite signs are placed on (diagonally) opposite corners of a 60-cm  80-cm rectangle. If point A is the corner of this rectangle nearest the positive charge and point B is located at the intersection of the diagonals of the rectangle, determine the potential difference, VB - VA.
 a. -47 V
  b. +94 V
  c. zero
  d. -94 V
  e. +47 V

Question 2

An alpha particle (m = 6.7  10-27 kg, q = +3.2  10-19 C) has a speed of 20 km/s at point A and moves to point B where it momentarily stops. Only electric forces act on the particle during this motion. Determine the electric potential difference VA - VB.
 a. +4.2 V
  b. -4.2 V
  c. -9.4 V
  d. +9.4 V
  e. -8.4 V
