Question

A simple pendulum takes 32 seconds to complete 20 oscillation.

What is the time period of the pendulum ?​

Answer 1

Given:

• Simple pendulum takes 32 seconds to complete 20 oscillation.

To find :

• Time period of pendulum?

Solution:

Given that simple pendulum is taking 32seconds to complete 20 oscillation.

We know that :

• $\large{\boxed{\sf{Time\: period\:=\:\dfrac{Time\:taken}{No.\:of\: oscillation}}}}$

Therefore,

$\large{\sf{Time\: period\:=\: \dfrac{time\:taken}{No.\:of\: oscillation}}}$

$\implies\large{\sf{Time\: period\:=\: \dfrac{32}{20}}}$

$\implies\large{\sf{Time\: period\:=\:\dfrac{8}{5}}}$

$\implies\large{\sf{Time\: period\:=\:1.6}}$

$\large{\boxed{\implies{\sf{\green{Time\: period\:=\: 1.6 seconds}}}}}$

Know more :

• Time period is defined as 'The time taken to complete one oscillation of a pendulum'.
• Oscillation is taken from a Latin words which means 'to swing'. So it is anything which moves back and forth. we can say it to and fro motion also.
