    If no external torque acts on a body, will its angular velocity remain conserved?

    Answer:

                    When \[\tau =0\], \[\text{L}=\text{I}\omega \]= constant. \[\therefore \]Angular velocity \[\omega \] will be constant so long as I remains constant i.e. if moment of inertia of the body about the given axis remains fixed.
