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 decided

Answer

B

Explanation

(b) Here forces applied should be on opposite directions. So net forces is zero. Their centre of mass wil remain at rest and finally they will meet at centre of mass. And centre of mass lies closer to `M`.
