# Derive the relation of Force between any two masses.

### 3 Answers | Add Yours

Let two object of mass `m_1,m_2` are separated by distance r.Let F be the force acting between these two objects. Then

force F is directly proportional to the product of masses and Force F is inversely proportinal to squar of distance between them.ie.

`F prop m_1 xxm_2`

`F prop(1/r^2)`

Thus combining these two laws

`F prop(m_1m_2)/(r^2)`

`F=G(m_1m_2)/r^2`

where G is universal gravitational constant.

I mean to ask by the method of dimension

Sorry it was slip /software problem,

mass is in Kg and distance taken in metre.

result force came in Newton.
