A string of length , tied to the top of a pole, carries a ball at its other end as shown. On giving the ball a single hand blow perpendicular to the string, it acquires an initial velocity in the horizontal plane and moves in a spiral of decreasing radius by curling itself around the pole. Therefore,


Options
- Athe instantaneous centre of revolution of the ball is the point of contact of the string with the pole at that instant.
- Bthe instantaneous centre of revolution of the ball will be fixed at the point where the string was initially fixed.
- Cthe angular momentum of the system will not be conserved.
- Dthe angular momentum of the system will be conserved.
Correct answer
C. the angular momentum of the system will not be conserved.
