Problem

A pendulum of length

1.20\,\text{m}

swings with a particular period on Earth where

g = 9.8\,\text{m/s}^2

. What length must a pendulum have on the Moon, where

g = 1.6\,\text{m/s}^2

, so that it has the same period as the Earth pendulum? a)

0.49\,\text{m}

7.4\,\text{m}

0.20\,\text{m}

0.16\,\text{m}
