By keeping moment of inertia of a body constant, if we double the time period, then angular momentum of body

By keeping moment of inertia of a body constant, if we double the time period, then angular momentum of body

How we define angular momentum of a body ?

Is moment of inertia of a body a constant quantity?

By keeping moment of inertia of a body constant, if we double the time period, then angular momentum of body A. remains constant B. becomes half C. Doubles D. Quadruples

A body of moment of inertia 2kg-m^2 has a rotational kinetic energy 4J. What is the angular momentum of the body ?

A body of moment of inertia 2kg-m^(2) has a rotational kinetic energy of 4 J. What is the angular momentum of the body ?

(A) : When there is no external torque moment of inertia of a rotating body changes, its angular momentum remain conserved, but its kinetic energy changes. (R ) : Angular momentum does not depend upon moment of inertia of the body.

If I is the moment of Inertia and E is the kinetic energy of rotation of a body , then its angular momentum is given by
