Question

How much will a person with 72 N weight on the earth weigh on the
moon?
(a) 12 N (b) 36 N (c) 21 N (d) 63 N​

Answer 1

Answer:

a==>12N

weight on moon=weight on earth/6

=72/6=12N

Answer 2

Weight on moon will be - (a) 12 N.

Gravity on earth is related to gravity on moon by the formula -

mg(moon) = mg/6(earth)

Mg = weight.

In the formula, m is mass and g refers to acceleration due to gravity.

This means gravity on moon is 1/6 of gravity on earth.

Since weight on earth is given 72 N, hence weight on moon according to above formula will be -

Weight on moon = 72/6

Weight on moon = 12 N

Hence, weight on moon of given weight on earth will be - 12N
