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 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

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

A particle performing uniform circular motion has angular momentum L . When its angular velocity is doubled and K.E is also doubled, the new angualr momentum becomes x times. What is x ?

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

The angular momentum of electron can have the value (s) :

A particle attached to a string is rotating with a constant angular velocity and its angular momentum is L. If the string is halved and angular velocity is kept constant, the angular momentum will be
