Question

How much would a 70 kg man weigh on moon?What will be his mass on earth and moon?Given g on moon is =1.7m/s2.​

Answer 1

Answer:

As mass is same everywhere so the man would weigh 70 kg on moon as well as on earth.

acceleration due to gravity(g)=9.8 m/s2

Weight of man on earth(We)=mg

=70*9.8

=686 N

Weight of man on moon(Wm)=686/6

=114.34 N (approx.)

Answer 2

Answer:

we know ,

the weight on moon is 1 / 6 of earth .

therefore,

weight on Earth = 70 kg .

$weight \: on \: moon \: = \frac{1}{6} \times 70$

$= 11.66 \: \: kg \: .$

and in terms of Newton,

weight = mass × g

weight = 70 × 1.7

weight = 119 N .

Note :-

• Mass remains constant .

• Mass on Earth and Moon will be same .
