Tie a small piece of stone to one end of a string and whirl it in a circle with your hand The centripetal force required by the stone is being supplied by your hand through the string If the string breaks suddenly you observe that the stone flies off along the tangent to the circle at that instant . Read the above passage and answer the following questions:
(i) Why does the stone fly off along the tangent to the circle at the instant the string breaks
(ii) What lessons of life do you learn from this study ?

Explanation

### Step-by-Step Solution

**(i) Why does the stone fly off along the tangent to the circle at the instant the string breaks?**

1. **Understanding Circular Motion**: When the stone is being whirled in a circle, it is undergoing circular motion. For an object to maintain circular motion, it requires a centripetal force directed towards the center of the circle.

2. **Role of Tension in the String**: In this scenario, the tension in the string provides the necessary centripetal force. This force acts perpendicular to the stone's instantaneous velocity, which is directed tangentially to the circle.
