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 an angular momentum L. If the length of string and angular velocity, both are doubled, the new angular momentum is

A mass is whirled in a circular path with an angular momentum L . If the length of string and angular velocity, both are doubled, the new angular momentum is

A mass is whirled in a circular path with an angular momentum L. If the length of string and angular velocity,both are doubled the new angular momentum is NL. Find the value of N
