Consider a two particle system with particles having masses $${m_1}$$ and $${m_2}$$. If the first particle is pushed towards the center of mass through a distance $$d,$$ by what distance should the second particle is moved, so as to keep the center of mass at the same position?

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

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

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

$$d$$

A T shaped object with dimensions shown in the figure, is lying on a smooth floor. A force $$'\,\,\overrightarrow F \,\,'$$ is applied at the point $$P$$ parallel to $$AB,$$ such that the object has only the translational motion without rotation. Find the location of $$P$$ with respect to $$C.$$ AIEEE 2005 Physics - Center of Mass and Collision Question 111 English
