Question
A bead is free to slide down a smooth wire tightly stretched between points A and B on a vertical circle. If the bead starts from rest at A, the highest point on the circle
- its velocity v on arriving at B is proportional to cos
- its velocity v on arriving at B is proportional to tan
- time to arrive at B is proportional to cos
- time to arrive at B is independent of
The correct answer is: its velocity v on arriving at B is proportional to cos
