A parallel-plate capacitor is connected to a battery and becomes fully charged.
 
  The capacitor is then disconnected, and the separation between the plates is increased in such a way that no charge leaks off. As the plates are being separated, the energy stored in this capacitor
  A) increases. B) become zero. C) does not change. D) decreases.

Question 2

A photon of initial wavelength 0.651 nm, after being scattered from a free electron at rest, moves off at an angle of 120 with respect to its incident direction.
 
  (mel = 9.11  10-31 kg, h = 6.626  10-34 J  s, c = 3.00  108 m/s)
  (a) What is the wavelength of the scattered photon?
  (b) What is the energy of the scattered photon?
