Q. The centre of mass of a system of two particles divides the distance them
A) In inverse ratio of square of masses of particles
B) In direct ratio of square of masses of particles
C) In inverse ratio of masses of particles
D) In direct ratio of masses of particles
Explanation
(c) $m_{1}r_{1} = m_{2}r_{2}$
$\frac{r_{1}}{r_{2}} = \frac{m_{2}}{m_{1}}\ \ \ \therefore r \propto \frac{1}{m}$
