An object is located inside a thin, uniform density spherical shell. At what locations would the object not be subject to a net gravitational force?
 
  A)
 
  only against the inside boundary of the shell
  B)
 
  only at locations on a sphere that is one-half the inside radius of the shell
  C)
 
  anywhere within the shell
  D)
 
  only at locations on a sphere that is one-half the mean radius of the shell
  E)
 
  only at the center of the shell

Question 2

Traveling waves are created on a rope that has a mass per length 0.200 kg/m that is stretched with a tension of 400 N.
 
  If the end of the rope is moved up and down with simple harmonic motion with amplitude 30.0 cm and a period 1.40 s, how much work is done in one period of the motion?
  A)
 
  133 J
  B)
 
  400 J
  C)
 
  267 J
  D)
 
  11.3 J
  E)
 
  No work is done because the tension pulls outward along the rope, but the end of the rope moves perpendicular to the rope.
