Solution:
As object is in circular motion angular momentum
\[ \vec L=I\vec\omega \]
Direction of omega is along the axis so, L will have direction along axis OC. So both magnitude
and direction of angular momentum L is constant.
A conical pendulum consists of a simple pendulum moving in a horizontal circle as shown. C is the pivot, O the centre of the circle in which the pendulum bob moves and ω the constant angular velocity of the bob. If L is the angular momentum about point C, then
