Question

Two particles of $m_1$ and $m_2$ approaching towards each other under their mutual gravitation field. If the speed of the first particle is $v,$ the acceleration of the center of mass of the system is equal to

• A. $\frac{m_1}{m_2}v$
• B. Zero
• C. Both of them
• D. None of them

Answer 1

The correct option is B Zero

The external forces acting on particles of the system sum to zero.

therefore acceleration is zero.

option (b) zero.
