149947 A disc of moment of inertia \(I_{1}\) is rotating with an angular velocity \(\omega_{1}\). Another disc of moment of inertia \(I_{2}\) which is not rotating, is gently put on the first disc. The angular speed of the system will be

149949 A rod ' \(l\) ' \(\mathbf{m}\) long is acted upon by a couple as shown in figure. The moment of couple is ' \(\tau\) ' \(\mathrm{Nm}\). If the force at each end of the rod, the magnitude of each force is
\(\ left(\sin 30^{\circ}=\cos 60^{\circ}=\frac{1}{2}\ right\)

149950 Three point masses each of mass ' \(m\) ' are kept at the corners of an equilateral triangle of side ' \(L\) '. The system rotates about the centre of the triangle without any change in the separation of masses during rotation. The period of rotation is directly proportional to \(\left(\cos 30^{0}=\right.\) \(\sin 60^{0}=\sqrt{3} / 2\)
