A string of length 90 cm is fastened to two points and at the same level 60 cm apart. A ring weighing 120 g is slided on the string. A horizontal force is applied to the ring such that it is in equilibrium vertically below . The value of is:

Applied mechanics is the branch of science concerned with the motion of any substance that can be experienced or perceived by humans without the help of instruments. In short, when mechanics concepts surpass being theoretical and are applied and executed, general mechanics becomes applied mechanics.
