Physics - W.E.P. Question with Solution | TestHub

A rod is fixed between a vertical wall and a horizontal surface. A smooth ring of mass 1 kg is released from rest which can move along the rod as shown. At the release point spring is vertical and relaxed. The natura length of the spring is $(\sqrt{3}+1)\mathrm{m}\left(\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right)$ Rod makes an angle of $30^{\circ }$ with the horizontal. Ring again comes to rest when spring makes an angle of $30^{\circ }$ with the vertical.
