Question

The weight of a body is 60N.Find its mass.( g=10 m/ 2 )​

Answer 1

Explanation:

Hint:Mass of the body is a constant quantity and the acceleration due to the gravitational force on the moon is equal to approximately six times the acceleration due to the gravitational force on earth.

Complete step by step answer:

From the given question, we know that the weight of the body on earth is,

We=60kgWe=60kg.

We know that the weight of a body on earth is equal to the product of mass of the body and acceleration due to gravity (gravitational force on earth).

We=mgeWe=mge

We know that the value of acceleration due to gravity (gravitational force on earth) is 9.8m/s29.8m/s2

Since we know that the mass is a constant quantity. It does not depend on the location of it.

Substitute the given values in the above equation, we get,

60=mge60=mge

⇒m=609.8kg⇒m=609.8kg

The acceleration due to the gravitational force on the moon is equal to approximately six times the acceleration due to the gravitational force on earth.

gm=6gegm=6ge

The weight of the body on the moon is expressed as,.

Wm=mgmWm=mgm

Rewrite the above equation,

Wm=m(6ge
