Question

a body of mass M 20 kilometres is taken from earth to moon find its weight on Earth​

Answer 1

Explanation:

As we know a body's weight is the product of its mass and acceleration acting on it i.e

W=ma

given, m=20kg

here acceleration (a) would be g=10m/s²

{because on Earth a body experiences acceleration and due to gravity (g)}

so, weight of the body on Earth is 

W=20×10=200kg

as we know, 

weight on moon=61 weight on earth

so weight on moon=6200=33.33kg
