Question

1What is the mass and weight of a body on the moon if its weight is 120 N on the earth ?
(g = 9.8m/s^2)​

Answer 1

Answer:

Explanation:in moon the weight is 1/4,so answer is-

1/4×120=30 (ans)

Answer 2

The acceleration due to gravity on moon is 1/6th of that on Earth.

120 N means that the weight has already been converted from kg to N by multiplying it with g hence we can directly divide it by 6.

Therefore the weight of this body on moon is 120 ÷ 6 = 20 N

You can also obtain the answer using percentage concept because the weight of a body on moon is 16 % of that on the Earth.
