Question 46 of 130

Consider a two particle system with particles having masses m1m_1 and m2m_2. If the first particle is pushed towards the centre of mass through a distance dd, by what distance should the second particle be moved, so as to keep the centre of mass at the same position?

Show answer and solution

Answer: (D) m1 m2 d\frac{\mathrm{m}_1}{\mathrm{~m}_2} \mathrm{~d}

m1d+m2x=0m_1 d+m_2 x=0
x=m1dm2x=\frac{m_1 d}{m_2}
