Two protons, each of charge 1.60  10-19 C, are 3.00  10-5 m apart. What is the change in potential energy if they are brought 1.00  10-5 m closer together? (ke = 8.99  109 Nm2/C2)
 a. 3.84  10-24 J
  c. 1.15  10-23 J
  b. 3.20  10-16 J
  d. 3.20  10-19 J

 a. 0 J
  c. 9.5 kJ
  b. -9.5 kJ
  d. -18 J
