Gravitational force with which a body attracts the other is always equal to the force with which the other attracts the first. Assuming no other forces acting on the bodies, choose the correct statement.

Options

A. Both the bodies always have equal acceleration
B. Both the bodies may have equal acceleration
C. Both the bodies may not have equal acceleration
D. The acceleration of the centre of mass of the two bodies is zero

Answer

B, C, D

Explanation

According to Newton’s third law, we have
`vecF_(AB)=-vecF_(BA)`
As their masses may be different, acceleration produced in them according to Newton’s second law `veca=vecF//m`
Also, as no external force acts `veca_"cm"=0`
