Two persons A and B of weight `80 kg` and `50 kg` respectively are standing at opposite ends of a boat of mass `70 kg` and length `2 m` at rest. When they interchange their positions then displacement of the centre of mass of the boat will be :-

Two boys A and B of masses 60kg and 40kg respectively are at the ends of a 4m long boat of mass 100kg which is on water in lake and the system is at rest.If the boys meet at the centre of the boat then find the displacement of centre of mass of the boat in meter (neglect friction between water and boat)

A boy of mass m is standing at one end of a boat of mass M and length l. The boy walks to the other end, the displacement of the

A boy of mass 50kg is standing at one end of a boat of length 9m and mass 400kg . He runs to the other end. The distance through which the centre of mass of the boat boy system moves is
