Three identical balls A, B and C each of mass m = 3 kg are connected by strings AB and BC as shown in the figure. The whole system is placed on a smooth horizontal surface. Now the ball B is given an initial velocity \[{{v}_{0}}=\sqrt{3}\] m/s, perpendicular to the string and along the horizontal surface. Find the tension (in Newton) in the string just before the balls A and C collide.
