Question

A simple pendulum takes 18 seconds to complete 10 oscillations what is time period of the pendulum?

Answer 1

time period = time taken to complete 1 oscillation
time period = 18 /10 s
=9/5 s
=1.8 second

Answer 2

The time period of the pendulum is 1.8 sec.

Explanation:

Given that,

Time = 18 second

Number of oscillations = 10

We need to calculate the time period of the pendulum

Using formula of time period

$T = \dfrac{t}{n}$

Where, t = time taken

n = number of oscillation

Put the value into the formula

$T=\dfrac{18}{10}$

$T=1.8\ sec$

Hence, The time period of the pendulum is 1.8 sec.
