Answer 2

Answer: The correct option is option A.

The time period of a pendulum is 1.2s

Explanation:

A pendulum needs to go,

• From mean position to one side - 0.3s
• From that one side back to mean position - 0.3s
• From that mean position to another end - 0.3s
• From that another side back to mean position - 0.3 s.

That means, the total time period of a pendulum is (0.3 + 0.3 + 0.3 + 0.3)s = $4 * (0.3)s$ = 1.2s

Hence, The correct option is option A.

The time period of a pendulum is 1.2s.
