  You place both objects at the same distance from a powerful light source so they both receive the same amount of energy U from the light. The linear momentum these objects will receive is such that: A)
 
  The reflecting objects receives a larger amount of momentum.
  B)
 
  Both objects receive the same amount of momentum.
  C)
 
  The reflecting object receives a smaller amount of momentum.
