Question

A pendulum of length =1.0 m is pulled to the side and released on the moon. It's period is measured to be 4.82 seconds. What is the gravity on the moon?

Answer 1

Answer:

Gravity on the moon, g = 1.69 m/s²

Explanation:

It is given that,

Length of pendulum, l = 1 m

Time period, T = 4.82 seconds

We have to find the gravity of the moon. The time period of the pendulum is given by :

$T=2\pi\sqrt{\dfrac{l}{g}}$

g = acceleration due to gravity on moon

$g=\dfrac{4\pi^2l}{T^2}$

$g=\dfrac{4\pi^2\times 1\ m}{(4.82\ s)^2}$

g = 1.69 m/s²

Hence, the gravity on the moon is 1.69 m/s².

Answer 2

Answer:

Gravity on the moon, g = 1.69 m/s²

Explanation:

If the pendulum of length is 1.0 m is pulled to the side and released on the moon and It's period is measured to be 4.82 seconds, the gravity on the moon is 1.69 m/s².
