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

Options

A. Inclined at a angle of `60^(@)` from vertical
B. The mass is at the highest point
C. The wire is horizontal
D. The mass is at the lowest point

Answer

D

Explanation

In vertical circular motion, tension in wire will be maximum at lower most point, so the wire is most likely to break at lower most point. `(T = sqrt(5gl))`
