Observe Figure

The time period of a simple pendulum is the time taken by it to travel from _____________.

• A. O to B, B to A and A to O
• B. O to A, A to B and B to A
• C. B to A, A to B and B to O
• D. A to B

Answer 1

The correct option is A O to B, B to A and A to O

Time period of a simple pendulum is the total time taken to complete one full cycle, i.e. by coming to its initial position.
Therefore if the bob starts from O towards B, to complete one full cycle(time period), it must move from O to B, B to A and A to O.
