Statement II: The acceleration due to gravity have no effect on time period of watch at the time of filling

• A. If both statement $I$ and statement II are true and statement II is the correct explanation of statement $I$.
• B. If both statement $I$ and statement II are true but statement II is not the correct explanation of statement $I$.
• C. If statement $I$ is true but statement II is false.
• D. If both statement $I$ and statement II are false.

Answer 1

Answer: (A)

When the man falls from the top of a tower, he will be in the state of weightlessness. A spring wound watch runs on the basis of spring action i.e., on the basis of the potential energy stored in the wound spring. Since, acceleration due to gravity does not play any role, the watch will give correct time, when the man falls from the top of a tower.
