Question

In the figure given below, the time taken by the bob to reach from point O to B is T.

The total distance covered by the pendulum and the time taken to complete one oscillation is:

• A. x, T
• B. 2x, 4T
• C. 4x, 4T
• D. 8x, 6T

Answer 1

The correct option is C 4x, 4T

The pendulum is said to complete one oscillation when it follows the path O – B – O – A – O.
The distance O - B is x. Hence in one complete oscillation, the distance covered is 4x.
Also, the time taken for the bob to go from O to B is T. Thus, the time taken for one complete oscillation is 4T.
