A mass is whirled in a circular path with an angular momentum L . If the length of string is now halved keeping the angular velocity same, the new angular momentum is

A mass is whirled in a circular path with constant angular velocity and its angular momentum is L. If the string is now halved keeping the angular velocity the same, the angular momentum is

A mass is whirled in a circular path with a constant angular velocity and its angular momentum is L. If the string is now halved keeping the angular velocity same, the angular momentum is
