Question

6. The weight of a body on the earth is 120 N. The weight of the same body on the moon will be​

Answer 1

Given :

• Weight of a body on the earth = 120 N

To find :

• Weight of the same body on the moon

Solution :

Weight of the same body on the moon will be 20 N.

Explanation :-

Weight is the product of mass and gravity.

Weight = mass × gravity

Gravity on the moon is 1/6 th of the gravity on the earth.

Weight changes with respect to gravity. As gravity on the moon is 1/6 th of the gravity on the earth. So, the weight of the body will be 1/6 th of the weight of the body on the earth.

So, if a body weighs 120 N on earth it will will weigh 120 × 1/6 on moon ,i.e.. 20 N.
