A simple pendulum has a time period of

2.0\,\text{s}

on Earth where

g_{\text{Earth}} = 9.8\,\text{m\,s}^{-2}

. If the same time period is to be obtained on the Moon where

g_{\text{Moon}} \approx 1.6\,\text{m\,s}^{-2}

, what should be the approximate length of the pendulum on the Moon? (a)

0.67\,\text{m}

(b)

0.16\,\text{m}

(c)

6.4\,\text{m}

(d)

1.0\,\text{m}
