Solution

Q.
A mass $m$ is attached to a thin wire and whirled in a vertical circle. The wire is most likely to break when [2019]

1 inclined at an angle of $60 °$ from vertical

2 the mass is at the highest point

3 the wire is horizontal

4 the mass is at the lowest point

Ans.
(4)

In vertical circular motion, tension in the wire is maximum at the lowermost point, so the wire is most likely to break when the mass is at the lowermost point.
