A thin spherical metal shell of radius 8.0 cm carries 7.5 C of excess charge. What is the magnitude of the electric field it produces at the following places?
 
  (k = 1/40 = 9.0  109 N  m2/C2 )
  (a) at 1.0 cm above the surface
  (b) at 7.0 cm from the center of the sphere

Question 2

A space barge pushes on a spaceship with a rest mass of 15,000 kg and accelerates it from a speed of 0.600c to a speed of 0.700c. How much work does the barge have to do to accomplish this? (c = 3.00  108 m/s)
 
  A) 2.03  1020 J B) 2.70  1020 J C) 8.78  1019 J D) 5.42  1020 J E) 1.35  1020 J
