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 is now halved keeping the angular velocity same, the new angular momentum is

If the unit of mass , length and the time are doubled then unit of angular momentum will be

If the unit of mass , length and the time are doubled then unit of angular momentum will be

A mass is supported on a frictionless horizontal surface. It Is attached to a string and rotates about a fixed center at an angular velocity omega_(0) .If the length of the string and angular velocity both are doubled, the tension in the string which was initially T_(0) is now

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
