Question

the mass of body at moon is 40 kg what will be weight at earth​

Answer 1

Explanation:

Note that in the metric system of units, a kilogram (kg) is a unit of mass, not weight. If an object has a mass of 40 kg on Earth it will have the same mass on the Moon. But, on a scale on Earth the 40 kg mass will weigh about 88 pounds. On the Moon it would weight about 14.7 lbs because the gravity there is 1/6 that on the surface of the Earth.

Answer 2

Answer:

The mass of anything is constant no matter whether it's on the moon or the Earth (this fact is incomplete however, for higher standards, and not exactly correct).

So, the mass on Earth too, shall be 40kg.

Now, weight = mass * gravitational acceleration.

For Earth, gravitational acceleration constant =

So, weight = 40 kg * (9.8) = 392 Newtons.
