A shell explodes in a region of negligible gravitational field giving out n fragments of equal mass m Then its total 1 Kinetic energy is smaller than that before the explosion 2 Kinetic energy is equal to the before the explosion 3 Momentum and kinetic energy depend on n 4 Momentum is equal to that before the explosion
