Two masses m1 and m2(m1<m2) are released from rest from a finite distance. They start under their mutual gravitational attraction-
Acceleration of m2 is more than that of m1
Acceleration of m1 is more than that of m2.
Centre of mass of system will remain at rest in all the reference frame
Total energy of system remains constant

Solution
Verified by Toppr
Mutual force of
attraction is same on two bodies, but acceleration a=Fm
Therefore, a∝1m
As m1<m2, ⇒a2<a1
Here, Potential energy
is getting converted to kinetic energy.
Therefore, no energy
loss.
