Question #5cb0c

Answer 1

`F=(G*M_1*M_2)/r^2`

Explanation:

The force of attraction between two bodies having masses is called as Gravitational force.

Gravitational force is directly proportional to product of masses of the two bodies .

`F alpha M_1*M_2`

Gravitational force is inversely proportional to the square of the distance between the two bodies.

`Falpha1/r^2`

where,
r is the distance between two bodies.

Combining these two relations,
`Falpha(M_1*M_2)/r^2`

After inserting a proportionality constant in this equation we arrived at the relation,

`F=(G*M_1*M_2)/r^2`

Where ,

G is the Universal gravitational constant whose value is `6.67xx10^-11 Nm^2kg^-2`
