A conical pendulum consists of a simple pendulum moving in a horizontal circle as shown in the figure. C is the pivot, O is the centre of the circle in which the pendulum bob moves and ω the constant angular velocity of the bob. If  is the angular momentum about point C, then
    
  • a)
     is constant
  • b)
    only direction of  is constant
  • c)
    only magnitude of  is constant
  • d)
    None of the above
Correct answer is option 'C'. Can you explain this answer?

The direction of L is perpendicular to the line joining the bob to point C. Since this line keeps changing its orientation in space, direction of L keeps changing however as ω is constant, magnitude of L remain constant.
Aliter : The torque about point is perpendicular to the angular momentum vector about point C. Hence it can only change the direction of L, and not its magnitude.
