Question

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

Answer 1

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

= F = GMm/ R 2

Where G is the universal gravitational constant.

M is the mass of earth.

m is the mass of the object.

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

Answer 2

$\huge\underline{ \mathbb\red{❥A} \green{n} \mathbb\blue{S} \purple{w} \mathbb \orange{E} \pink{r}} \:$

$Let \: the \: mass \: of \: earth = M$

$Let \: the \: mass \: of \: the \: object =M$

$Distance \: between \: the \: earth's$

$and \: object =$

$Radius \: of \: the \: earth = R$

$Therefore,$

$Gravitational \: Force = F = GMm/ R 2$
