Question

In the figure given below:

The pendulum is said to complete one oscillation when it completes which one of the following paths?

• A. O – B – O
• B. O – B – O – A – O
• C. O – A – O
• D. O – B – O – A

Answer 1

The correct option is B O – B – O – A – O

One oscillation is a complete cycle of repetitive to and fro motion, from one extreme (maximum or minimum) to another (minimum or maximum) and back. Hence for completing one oscillation the path followed should be O – B – O – A – O.
