Inside a hollow uniform sphere of mass 'M', a uniform rod of lenght 'R $\sqrt{2}$ ' is released from the state of rest. The mass of the rod is same as that of the sphere. If the inner radius of the hollow sphere is 'R' then find out horizontal displacement of sphere with respect to earth in the time in which the rod becomes horizontal.
