Q: When a sailor jumps in the forward direction, the boat drifts backwards. Which law of Newton represent the example -
  • A. Second law of motion
  • B. First and second law of motion
  • C. Third law of motion
  • D. First law of motion
Correct Answer: Option C - Newton Third Law of Motion : According to this law, to every action, there is an equal and opposite reaction. When a sailor jumps out of a rowing boat, the boat moves backwards. As the sailor jumps forwards, he applies a backward force (action) on boat and the boat moves backwards due to the force of reaction.
