A large mass M hangs stationary at the end of a light string that passes through a smooth fixed tube to a small mass m that moves around in horizontal circular path. If l is the length of the string from m to the top end of the tube and is angle between this part and vertical part of the string as shown in the fig, then time taken by m to complete one circle is equal to
