Question

a pendulum oscillates 50 times in 5 sec. find its time period and frequency

Answer 1

time period is 0.1sec
frequency is 10(sec)-1

Answer 2

The time period and the frequency of the pendulum is 0.1 seconds and 10 Hz.

Explanation:

Given that,

A pendulum oscillates 50 times in 5 sec. We need to find the time period and the frequency of the pendulum.

We know that the frequency of an object is given by total number of oscillations per unit time. So,

$f=\dfrac{n}{t}\\\\f=\dfrac{50}{5}\\\\f=10\ Hz$

The time period is reciprocal of the frequency of an object. So,

$T=\dfrac{1}{f}\\\\T=\dfrac{1}{10}\\\\T=0.1\ s$

So, the time period and the frequency of the pendulum is 0.1 seconds and 10 Hz.
