    A stone tied to one end of a string is whirled in a circle. If the string breaks, the stone flies off tangentially. Why?

    Answer:

                    The velocity of the stone at any instant is along the tangent to the circle at that instant. When the string breaks, centripetal force whirling the stone vanishes. Therefore, on account of inertia, the stone flies off tangentially.
