A mass \(m\) is attached to a thin wire and whirled in a vertical circle. The wire is most likely to break when
- A the mass is at the highest point
- B the wire is horizontal
- C the mass is at the lowest point
- D inclined at an angle of \(60^{\circ}\) from vertical
Answer & Solution
Correct Answer
(C) the mass is at the lowest point
Step-by-step Solution
Detailed explanation
\(\mathrm{T}-\mathrm{mg} \cos \theta=\frac{\mathrm{mv}^{2}}{\mathrm{R}}\) \(T\) will be maximum when \(\theta=0^{\circ}\)
