Two bodies `A and B` have masses `M and m` respectively where `M gt m` and they are at a distance `d` apart. Equal force is applied to each of them so that they approach each other. The position where they hit each other is :

Options

A. nearer to B
B. nearer to A
C. at equal distance from A and B
D. cannot be determined

Answer

B

Explanation

As net external force on the system is zero therefore position of their centre of mass remains unaffected i.e. they will hit each other at the point of centre of mass. The centre of mass of the system lies nearer to A because `M_(A)gtM_(B)`.
