Two masses `m_(1)` and `m_(2) (m_(1) lt m_(2))` are released from rest from a finite distance. They start under their mutual gravitational attraction

Options

A. acceleration of `m_(1) ` is more than that of `m_(2)`
B. acceleration of `m_(2)` is more than that of `m_(1)`
C. centre of mass of system will remain at rest in all the reference frame
D. total energy of system does not remains constant

Answer

B

Explanation

Same force acts on both masses
Hence a `prop (1)/(m)` (F = ma)
In absence of external force (remember mutual) gravitational force is an internal force for the system ) total energy remains constant .
