A particle revolves uniformly along a circle on a smooth horizontal table by means of a string connected to it. Does angular momentum of the particle change from its initial value if string is cut suddenly? What is the value of angular momentum?

Solution

$When a particle revolves in a horizontal circular path and when the string imparting this angular momentum is cut then its angular momentum is changed . It becomes zero because as soon as string is cut the particle moves in a straight line, so there is no angular speed .$
