If you whirl a stone on the end of the string and the string suddenly ...
Explanation:
When a stone is whirled on the end of a string and the string suddenly breaks, the stone will fly off along the tangent to its circular path. This can be explained by the following points:
Centripetal Force:
When the stone is whirled on the end of a string, it moves in a circular path because of the centripetal force acting on it. This force is provided by the tension in the string. The tension in the string pulls the stone towards the center of the circle and keeps it in circular motion.
Tangential Velocity:
The stone also has a tangential velocity, which is perpendicular to the centripetal force. This velocity is responsible for the stone's motion along the circular path.
String Breaks:
If the string suddenly breaks, there will be no tension in the string to provide the centripetal force. As a result, the stone will continue to move along the tangent to its circular path with the same tangential velocity it had at the point where the string broke.
Inertia:
The stone will continue to move along the tangent due to its inertia. Inertia is the property of an object that causes it to resist any change in its state of motion. Since the stone was moving in a circular path, it will continue to move in the same direction along the tangent due to its inertia.
Conclusion:
Thus, the stone will fly off along the tangent to its circular path when the string suddenly breaks. This can be observed in real life when a person whips a yo-yo or a ball on a string and accidentally lets go of the string. The yo-yo or ball will fly off along the tangent to its circular path.

If you whirl a stone on the end of the string and the string suddenly ...
The correct option is A because when a stone is whirling around ,tied to a string its direction of the motion is constantly changing ,even if the speed/velocity is uniform.At the time of the string breaking,the stone because of it inertia of motion follows the direction which it had at the time of string breaking,which is mostly the tangent.
