Question

A man weighs 600N on earth.What would be his approximate weight on moon. Give reason.

Answer 1

it will be the 1/6 of his weight on earth which is 100N

Answer 2

Answer:

Weight on  moon = 97.2 N  

Weight - 60 Kg

Explanation:

A man weighs 600N on earth.What would be his approximate weight on moon - 97.2 N  .

Points to note:

1) Mass of an object remains constant anywhere.

2) Weight of an object varies depending on the gravitational acceleration of the surface.

Important constants are as follows:

Gravitational constant on moon = 1.62 m/s²

Gravitational constant on earth = 10 m/s²

Force = Mass × acceleration

Now :

600 = 10 × m  

m = 600/10 = 60 kg

The weight of the man on moon is givn as :

Weight = mass × gravitational acceleration on moon.

Weight on  moon = 1.62 × 60 = 97.2

= 97.2 N
