Question:-

what will be the weight of an astronaut on the moon if he weighs 72 kg on the earth?

Solution:-

$\sf\underline{ \rm {given}}$

Weight of astronaut is 72 kg on earth.

$\sf\underline{ \rm {to \: find \: }}$

the weight of astronaut on moon.

______________________

According to formula,

$\sf{ \rm \red{weight \: on \: moon = ( \frac{1}{6}th \: weight \: on \: earth}} \\ \frac{1}{6} \times 72 = 12\sf\underline{ \rm \red{}} \: kg$

Answer 2

Answer:

Explanation:

Let me clear you one thing....

Units of mass (m)= kg

Units of weight (W)= m*g = kg.m/sec²= Newtons... Where 'g' is acceleration due to gravity.

From your question you said your weight is 70 kgs, which is false...

It is your mass (m)= 70 kgs.

Your weight on earth = 70*9.81= 686.7 N (g= 9.81 m/sec²).

Your weight on moon =70*1.62= 113.4 N (g= 1.62 m/sec²).

Your weight on moon will be around 1/6th of weight on earth..

But your mass of 70 KGS remains same every where...
