Question

a simple pendulum takes 30 seconds to complete 15 oscillations.Calculate the time period of simple pendulum?

Answer 1

Answer:

time taken to complete 15 oscillations = 30s

time taken to complete 1 oscillations = 30÷2 = 2s

Answer 2

The time period of simple pendulum is 2 sec.

Given

Pendulum takes 30 seconds for 15 oscillations

To Find

We have to calculate the time period of the pendulum.

Solution

A mechanical system in which oscillatory motion takes place is known as the simple pendulum.

The only factors on which the period  of a simple pendulum depend are the value of g and the length of the string.

Pendulum takes 30 seconds for 15 oscillations.

For one oscillation it will take,

                            T = $\frac{30}{15}$ = 2 sec

Hence the time period is 2 sec.
