Three identical sphere of radius R are placed on horizontal surface touching one another. If one of the sphere remove then find the shift in centre of mass. Three identical sphere of radius R are placed on horizontal surface touching one another. If one of the sphere remove then find the shift in centre of mass.
Initial centre of mass of 2 spheres will be at the centre of the line joining the centre of the spheres . Let this point be at x = 0 , Now after removal of one sphere centre of mass of other sphere will be at its centre i.e. at x = R . So shift in centre of mass is R.
