Question

A pendulum has a length of 0.7 meter and a mass of 200 grams. Calculate the period (in seconds) of the pendulum.

Answer 1

1.6784 sec

Step-by-step explanation:

Length of the pendulum is given as L =0.7 meter

Acceleration due to gravity
`g=9.8m/sec^2`

Time period of the pendulum is given by
`T=2\pi \sqrt{(L)/(g)}`

Here L is the length of the pendulum and g is the acceleration due to gravity

So time period
`T=2\pi \sqrt{(L)/(g)}=2* 3.14\sqrt{(0.7)/(9.8)}=1.6784sec`

So time period of the given pendulum is 1.6784 sec
