A heavy mass is attached to a thin wire and is whirled in a vertical circle. The wire is most likely to break

Physics-General

When the mass is the lowest point of the circle
At an angle of $\cos^{- 1} (1 / 3)$ from the upward vertical
When the mass is at the highest point of the circle
When the wire is horizontal

Answer:The correct answer is: When the mass is the lowest point of the circleBecause here tension is maximum
