A particle (mass = 6.7  10-27 kg, charge = 3.2  10-19 C) moves along the positive x axis with a speed of 4.8  105 m/s. It enters a region of uniform electric field parallel to its motion and comes to rest after moving 2.0 m into the field. What is the magnitude of the electric field?
 a. 2.0 kN/C
  b. 1.5 kN/C
  c. 1.2 kN/C
  d. 3.5 kN/C
  e. 2.4 kN/C

Question 2

A particle (charge = +2.0 mC) moving in a region where only electric forces act on it has a kinetic energy of 5.0 J at point A. The particle subsequently passes through point B which has an electric potential of +1.5 kV relative to point A. Determine the kinetic energy of the particle as it moves through point B.
 a. 3.0 J
  b. 2.0 J
  c. 5.0 J
  d. 8.0 J
  e. 10.0 J
