Question

Two bodies of masses `m1` and `m2` are separated by a distance `R`.The distance of the centre of mass of the bodies from the mass `m1` is `A.(m2R)/(m1+m2)`. `B(m1R)/(m1+m2)` #C. (m1m2R)/(m1+m2) ?

Answer 1

`A`

Explanation:

Let the centre of mass of the system lies at a distance `x` from `m_1`,

so,we can say,

`(m_1 +m_2)x=m_1*0 +m_2R`

or, `x=(m_2R)/(m_1+m_2)`
