Show me the steps to solve $2.$ Two balls of masses $1$ kg each are connected by an inextensible massless string. The system is resting on a smooth horizontal surface. An impulse of $10$ Ns is applied to one of the bails at an angle $\backslash (30^\{\backslash$circ$\}\backslash )$ with the line joining two balls in horizontal direction as shown in the figure. Assuming that the string remains taut after the impulse, find the magnitude of impulse of tension in newton second. $($Take $\backslash (\backslash$sqrt$\{3\}=1\mathrm{.}7\backslash )).$
