Analyse the following 1 If two particles are moving towards each other under the action of mutual attractive force then they will collide at the centre of mass of the system i If a bomb at rest explodes then fragments fly off in different directions But centre of mass of the system remains at rest iii When a shell projected from ground explodes in mid air the fragment fly off in different directions describing their own parabolic paths But the centre of mass of all fragments would still continue to move along the same parabolic path along which it was moving before explosion iv Consider a system of two particles having masses m and m If m is pushed towards the centre of mass of the system through a distance d then to keep the centre of mass at the same position m has to be moved through a distance m m d v A uniform stick having very large height is placed vertically on the surface of earth Its centre of mass coincides with centre of gravity 1 i ii and iii are correct 3 iv and v are correct 2 i ii and iv are correct 4 i ii iii and iv are correct
