    Answer:

    The angular momentum (about the same axis) of the object is constant

    Explanation:

    Torque is the time time derivative of angular momentum.

    τ = dL / dt

    where;

    dL  is the change in  angular momentum

    τ is torque acting on the object

    dt is change in time

    when net torque acting on an object is zero, then

    dL / dt = 0

    Change in angular momentum (ΔL) is zero, therefore we can say that the angular momentum (L) is constant.

    Thus, the angular momentum (about the same axis) of the object is constant.
