Question

The mass and weight of an object are 5kg and 49 N respectively. What will be their values on the moon ? Assume that the acceleration due to gravity on the moon is 1/6 th of that the earth.

Answer 1

Hey.

Here is the answer.

Mass on moon will be same 5kg as mass remains constant .

Since weight = mg
so, 49N = 5kg × g
so, g = 49/5 m/s^2 on earth
as, g of moon is 1/6 th of g on earth
so, g on moon = 49/(5×6)=49/30 m/s^2

So, weight on moon = 5kg × 49/30 m/s^2
=49/6 N = 8.1667 N

Thanks.
