In the figure a uniform rod of mass `'m'` and length `'l'` is hinged at one end and the other end is connected to a light vertical of spring constant `'k'` as shown in figure. The spring has extension such that rod is equilibrium when it is horizontal . The rod rotate about horizontal axis passing through end `'B'`. Neglecting friction at the hinge find `(a)` extension in the spring `(b)` the force on the rod due to hinge.img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/RES_PHY_DPP_62_XI_E01_502_Q01.png" width="80%"
