An alpha particle (m = 6.7  1027 kg, q = +3.2  1019 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

Question 2

A particle (m = 2.0 g, q = 5.0 C) 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
