Capacitor 1 has parallel plates of length L and width W, plate separation d, and is filled with dielectric with constant K.Capacitor 2 has parallel plates of length 2L and width 2W, plate separation 2d, and is filled with dielectric with constant 2k. If a voltage V is applied to capacitor 1 and a voltage 2V is applied to capacitor 2, which capacitor stores more energy and by what factor?
 a. Capacitor 2 by a factor of 8
  b. Capacitor 2 by a factor of 16
  c. Capacitor 1 by a factor of 4
  d. Both capacitors store the same energy.
