Question

Write the expression for the gravitational force between the earth and an object lying on the surface of the earth.​

Answer 1

Answer:

Write the formula to find the magnitude of the gravitational force between the earth and an object on the surface of the earth.

Let the mass of earth = M.

Let the mass of the object = m.

Distance between the the earth's centre and object = Radius of the earth = R.

Therefore,

Gravitational Force = F = GMm/ R 2

Answer 2

Answer:

The gravitational force between the earth and an object on the surface of the earth is

F=G Mm/d^2

Where G is the universal gravitational constant

M is the mass of the earth

m is the mass of the object on the surface of the earth

d is the distance between the two bodies
