A body weighs 30N on the surface of the earth.How much will it weigh on the surface of the moon?

Given :-

weight = 30N

To find :-

Weight of the body at surface of moon.

Soultion:-

${\mathtt{ \frac{1}{6} g_{earth} = g_{moon} \: }} \\ \\ \mathtt{and} \\ \\ \mathtt{w = mg} \\ \\ \mathtt{on \: \: moon ⇒ {g}^{′} = \frac{g}{6}} \\ \\ \mathtt{weight \: \: on \: \: moon = m {g}^{′}} \\ \\ = \mathtt {\frac{m {g}^{′} }{6}} \\ \\ = \mathtt{ \frac{30}{6}} \\ \\ \boxed{ = \mathtt{5N}}$
