  • A. Is zero
  • B. Cannot be determined
  • C. Is positive
  • D. Is negative
Correct Answer: Option A - If an object is rotated in a circular path, the work done on it is zero because the displacement in the circular path is zero.
A. If an object is rotated in a circular path, the work done on it is zero because the displacement in the circular path is zero.
