Vedclass · Answer

(B) When a stone is whirled in a circular path,its velocity vector is always directed along the tangent to the circle at any given point.When the string breaks,the centripetal force,which was responsible for keeping the stone in circular motion,vanishes.According to Newton's First Law of Motion,an object in motion continues to move in a straight line at a constant velocity unless acted upon by an external force. Therefore,due to the inertia of direction,the stone continues to move along the tangent at the point where the string broke.

$A$ stone tied to the end of a string is whirled in a circular path. Why does the stone move in the direction of the tangent at that point when the string breaks?
