1.	A uniform rod pivoted at its upper end hangs vertically. It is displaced through an angle of 60∘ and then released. Find the magnitude of the force acting on a particle of mass 'dm' at the tip of the rod, when rod makes an angle of 37∘ with the vertical.
Answer» A uniform rod pivoted at its upper end hangs vertically. It is displaced through an angle of 60 $^{\circ}$ and then released. Find the magnitude of the force acting on a particle of mass 'dm' at the tip of the rod, when rod makes an angle of 37 $^{\circ}$ with the vertical.
