Question

Calculate the period of a pendulum that has length = 1.0 m.

Answer 1

2 s

Step-by-step explanation:

length of the pendulum, L = 1 m

acceleration due to gravity, g = 9.8 m/s^2

The time taken by the pendulum to complete one oscillation is called time period of the pendulum.

The formula for the time period of the pendulum is given by

`T=2\pi \sqrt{(L)/(g)}`

`T=2\pi \sqrt{(1)/(9.8)}`

T = 2 s

Thus, the time period of the pendulum is 2 second.

A pendulum whose time period is 2 s is called second's pendulum.
