A parallel plate capacitor is constructed with Teflon (dielectric constant 2.1 ) between the plates. This 12.6 F capacitor has been charged to 1.5 volts. The Teflon is then pulled out (removed).
 
  (a) What charge was originally stored?
  (b) After removing the Teflon, what potential is across the plates?

Question 2

Car A (mass = 1000 kg) moves to the right along a level, straight road at a speed of 6.0 m/s. It collides directly with car B (mass = 200 kg) in a completely inelastic collision.
 
  What is the momentum after the collision if car B was initially at rest?
  A) 2.0 KN-s to the right
  B) 6.0 KN-s to the right
  C) 8.0 KN-s to the left
  D) 10. KN-s to the right
  E) zero
