Question

The bob of a simple pendulum takes 0.40 s to go from one extreme position to the mean position . calculate the time period of a pendulum.

Answer 1

0.40/times of pendulum take

so

0.40/1because they give no value

so

ans=0.40

Answer 2

Answer:

Time period= 4×0.40 sec =1.6 sec

Explanation:

Time period is the time taken to complete one oscillation, One oscillation will be equal to 4 times of the time taken by the bob from extreme position to the mean position.
