Correct answer and explanation

Correct answer: the stone flies off tangentially.

Explanation: āœ… Correct Answer: A) the stone flies off tangentially. šŸ“š Explanation: When a stone is whirled in a circle, its velocity at any point is directed along the tangent to the path. The string provides the centripetal force to keep it in a circle. If the string breaks, this force vanishes, and the stone continues its motion in its current direction, which is tangential to the circle.
