A projectile of mass 3m is projected from ground with velocity 20root2 m/s at an angle 45°.at highest point it explodes into two peices. one of mass 2m and the other of mass m. mass 2m falls at a distance of 100m from point of projection towards right of point of projection. if the distance (in m) of second mass from point of projection where it strikes the ground is nx10, then n is (g=10m/s^2)
