We know that CM=m1+m2m1x1+m2x2 After changing a position of m1 and to keep the position of C.M. same. C.M. =m1+m2m1(x1d)+m2(x2−d2) 0⇒d2=m1+m2m1d−m2d2=m2m1d
Consider a system of two particle having masses m1 and m2. If the particle of mas m1 is pushed towards the mass centre of particle through a distance d, by what distance would the particle of mass m2 move so as to keep the mass centre of particles at the original position?

The Sun rotates around its centre once in 27 days. What will be the period of revolution if the Sun were to expand to twice its present radius without any external influence? Assume the Sun to be a sphere of uniform density.
A sphere of radius $R$ is cut from a larger solid sphere of radius $2 R$ as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is: 
A ball of mass 0.5 kg is dropped from a height of 40 m . The ball hits the ground and rises to a height of 10 m . The impulse imparted to the ball during its collision with the ground is (Take $\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^2$ )
