If the particle of mass \(m_{1}\) is pushed towards the centre of mass of the particles through a distance ' \(d\) ', by what distance particle of mass \(m_{2}\) move so as to keep the centre of mass of particles at the original position?

149685 A point mass of \(10 \mathrm{~kg}\) is placed at the centre of earth. The weight of the point mass is

149686 A disc of mass ' \(M\) ' and radius ' \(R\) ' is rotating about its own axis. If one quarter part of the disc is removed then new moment of inertia of the disc about the same axis is

149687 A circular hole of radius \(3 \mathrm{~cm}\) is cut out from a uniform circular dise of radius \(6 \mathrm{~cm}\). The centre of the hole is at \(3 \mathrm{~cm}\), from the centre of the original disc. The distance of centre of gravity of the resulting flat body from the centre of the original disc is
