A heavy mass is attached to a thin wire and is whirled in a vertical circle. The wire is most likely to break
Options
- Awhen the mass is at the highest point of the circle
- Bwhen the mass is at the lowest point of the circle
- Cwhen the wire is horizontal
- Dat an angle of ⁻¹ ( 1 3 ) from the upward vertical
Correct answer
B. when the mass is at the lowest point of the circle
Step-by-step solution
The tension at the highest point is zero, but tension at the lowest point is 6 times the weight of the body. Hence, wire is most likely to break at the lowest point.
