MCQ (Single Correct Answer)

-1

Consider a system of two particles having masses m₁ and m₂. If the particle of mass m₁ is pushed towards the mass centre of particles through a distance d. by what distance would be particle of mass m₂ move so as to keep the mass centre of particles at the original position?

$${{{m_1}} \over {{m_1} + m{}_2}}$$d

$${{{m_1}} \over {{m_2}}}$$d

$${{{m_2}} \over {{m_1}}}$$d
