A uniform rod of mass M = 5 kg and length  = 90 cm rests on a smooth horizontal surface. One of the end of the rod is stroke in a horizontal direction at right angles to the rod, importing a linear momentum p = 3 Ns to the rod. During the subsequent motion, the force exerted by one half of the rod on the other half is –
