$m_{1}$ and $m_{2}$ are two bodies of masses separated by a distance $R$. The distance of the centre of mass of the bodies from the mass $m_{1}$ is

  • A
    $\frac{m_{2} R}{m_{1}+m_{2}}$
  • B
    $\frac{m_{1} R}{m_{1}+m_{2}}$
  • C
    $\frac{m_{1} m_{2}}{m_{1}+m_{2}} R$
  • D
    $\frac{m_{1}+m_{2}}{m_{1}} R$
