A simple pendulum of length `l` and bob of mass `m` is displaced from its equilibrium position `O` to a position `P` so that hight of `P` above `O` is `h` . If is then released. What is the tension in the string when the bob passes through the through the equilibrium position `O` ?  Neglect friction. `v` is the velocity of the bob at `O`
