If we whirl a stone at the end of a string in a vertical circle, it is likely to break when the stone is:
Correct answer: B. At the lowest point
- A. At the highest point
- B. At the lowest point
- C. At any point during motion
- D. At the point where gravity is not acting
Explanation
The tension in the string is maximum at the bottom (lowest point) of the vertical circle, and if this tension exceeds the strength of the string, it is likely to break

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
