A particle (m = 2.0 mg, q = -5.0 mC) has a speed of 30 m/s at point A and moves (with only electric forces acting on it) to point B where its speed is 80 m/s. Determine the electric potential difference VA - VB.
 a. -2.2 kV
  b. +1.1 kV
  c. -1.1 kV
  d. +2.2 kV
  e. +1.3 kV

Question 2

 a. +8.5 V
  b. -8.5 V
  c. -4.8 V
  d. +4.8 V
  e. -17 V
