Question

In an experiment to measure the time period of a simple pendulum, the time for 20 complete oscillations was found to be 36 s. What is the time period of this pendulum?

Answer 1

Step1 Given:-

Time taken to complete 20 oscillations is 36 sec.

Step2 Finding time period:

1. Time Period is defined as the time taken by the pendulum to complete one oscillation.
2. So time taken to complete 1 oscillation =$\frac{36}{20}$$sec$ = $1.8sec$
3. Hence time period of the pendulum is 1.8 sec.
