Question

What is gravitational field strength?

Answer 1

We know that gravitational force is the force on a body because of another body.

For a specific body , which have mass M will attract a body of mass m towards it.

So in this way , we can calculate , the gravitational force by the body of mass M.

That is F=GMm/R^2

But suppose we want to compare Two bodies of mass M1 and M2 that which body will apply much force.

In this case we will take the value of m =1.

So in this case we will find the Gravitational force on a unit mass .

So force on a specific distance by Bodies M1 and M2 on body m will be according to the masses of bodies M1 and M2.

This is called gravitational field strength.

That is E=GM(1)/R^2.

R= distance of bodies.

The body with more mass will have more strong gravitational field.
