A pendulum is made of a massless string of length and a small bob of negligible size and mass . It is released making an angle (<< 1 rad) from the vertical. When passing through the vertical, the string slips a bit from the pivot so that its length increases by a small amount ( ) in negligible time. If it swings up to angle on the other side before starting to swing back, then to a good approximation, which of the following expressions is correct?
