A simple pendulum of length L having a bob of mass m is deflected from its rest position by an angle θ and released (figure) The string hits a peg which is fixed at a distance x below the point of suspension and the bob starts going in a circle centred at the peg. If the pendulum is released with θ=90∘ and x = L2 find the maximum height reached by the bob above its lowest position before the string becomes slack.
None of these
