Question

A simple pendulum takes 42 s to complete 24 oscillations find out the time period of the pendulum

Answer 1

No. of oscillations completed by the pendulum= 42 

Time taken to complete 42 oscillation= 20 seconds 

Time period= No. of oscillations completed/Time taken 

Time period= 42/20 

= 21/10 (cancelled by 2) 

= 2.1 

Time period= 2.1 seconds

Answer 2

Given - Time and number of oscillations

Find - Time period

Solution - The time period of simple pendulum is 1.75 seconds

Time period of simple pendulum will be calculated by the formula = Time /number of oscillations

Time period = 42/24

Performing division to find the value of time period

Time period = 1.75 seconds

The time period of the simple pendulum is 1.75 seconds.
