A 60-mC charge is held fixed at the origin and a -20-mC charge is held fixed on the x axis at a point x = 1.0 m. If a 10-mC charge is released from rest at a point x = 40 cm, what is its kinetic energy the instant it passes the point x = 70 cm?
 a. 9.8 J
  b. 7.8 J
  c. 8.8 J
  d. 6.9 J
  e. 2.8 J

Question 2

A particle (charge = 5.0 mC) is released from rest at a point x = 10 cm. If a 5.0-mC charge is held fixed at the origin, what is the kinetic energy of the particle after it has moved 90 cm?
 a. 1.6 J
  b. 2.0 J
  c. 2.4 J
  d. 1.2 J
