Question

A simple pendulum takes 32 seconds to complete 20 oscillations. What is the time period of the pendulum?a

Answer 1

Time period of a simple pendulum is the time taken by the pendulum to complete one oscillation.

Here, to complete 20 oscillations, the simple pendulum takes 32 seconds.

So, to complete 1 oscillation, the simple pendulum takes 32 / 20 = 1.6 seconds.

Answer 2

Time period = Time taken / no of oscillation

= 32 / 20

= 8 / 5 = 1.6 s
