Two bodies \(\mathbf{P}\) and \(\mathbf{Q}\) of masses \(m_{1}\) and \(m_{2}\) \(\left(m_{2}\lt m_{1}\right)\) are moving with velocity \(v_{1}\) and \(v_{2}\) respectively, collide with each other. Then the force exerted by \(P\) on \(Q\) during the collision is
1 greater that the force exerted by \(Q\) on \(P\)
2 less than the force exerted by \(Q\) on \(P\)
3 same as the force exerted by \(Q\) on \(P\)
4 same as the force exerted by \(Q\) on \(P\) but opposite in direction
