Question

a simple pendulum takes 10 sec to complete 20 oscillation wat is the time period of the pendulum?​

Answer 1

Answer:

to complete 20 oscillations, what is the time period of the pendulum? Hint: Time period of a pendulum is time taken by it to complete 1 oscillation. Hence, the time period of the pendulum is 1.6 seconds.

Answer 2

Answer:

A simple pendulum takes 10 sec to complete 20 oscillations. The time period of the pendulum will be $0.5\ s$

Explanation:

The time period can be obtained from the ratio of time taken for the oscillations and the number of oscillations made by the pendulum.

Or

It is simply the time taken to complete one to and fro motion of the oscillating body.

Let T be the time period N  be the number of oscillations  and t be the time taken for the oscillations then,

        $T = \frac{t}{N}$      ....(1)

In the question, it is given that,

$t=10\ s$

$N = 20$

Substitute these values into equation(1)

$T = \frac{10}{20} = 0.5\ s$

• Time period of the pendulum = $0.5\ s$
