Two stars of mass `m_(1)` and `m_(2)` are parts of a binary star system. The radii of their orbits are `r_(1)` and `r_(2)` respectivey, measured from the centre of mass of the system. The magnitude of gravitational force `m_(1)` exerts on `m_(2)` is

A

`(m_1m_2G)/((r_1+r_2)^2)`

B

`(m_1G)/((r_1+r_2)^2)`

C

`(m_2G)/((r_1+r_2)^2)`
