3. 3.Which of the following statements correctly explains why the work done during a round trip is zero?
   • A.No force is required to move a body in its round trip.
   • B.Work done is zero only for conservative forces during a round trip.
   • C.The body does not return to its starting point.
   • D.The force applied is always perpendicular to the displacement.

5. 5.A ball is placed on a compressed spring. What form of energy does the spring possess? On releasing the spring, the ball flies away. Which of the following best explains this observation?
   • A.The spring possesses elastic potential energy, which converts to kinetic energy of the ball.
