A conical pendulum consists of a bob of mass m in motion in a circular path in a horizontal plane as shown in figure. During the motion, the supporting wire of length l . Maintains a constant angle theta with the vertical. The magnitude of the angular momentum of the bob about the vertical dashed line is. .
