Question

The mass of the body on moon is 40kg, what is the weight on the earth.
a. 240kg b. 392N c. 240N d. 400kg

Answer 1

(B) 392N.

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 = $9.8 m/s^2$

So, weight = 40 kg * ($9.8 m/s^2$) = 392 Newtons.

($kg-m/s^2$ = N)
