Question

A pendulum oscillates 60 times in 5 seconds . Find time period and frequency.

Answer 1

Given,

The pendulum oscillates 60 times in 5 second

So the number of oscillations per second is $\frac{60}{5}=12$

So the frequency is 12

Now,

We know

Time period

$T=\frac{1}{f}=\frac{1}{12}$ s

Hence the time period is $\frac{1}{12}s$
