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 followingquestions: (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 ?
