Vedclass · Answer

(A) At the highest point of its swing,the velocity of the pendulum bob is zero because it momentarily comes to rest before reversing its direction. When the string is cut at this instant,the only force acting on the bob is gravity,which acts vertically downwards. Since the initial velocity is zero and the acceleration due to gravity is directed downwards,the bob will fall vertically downwards in a straight line. Therefore,the correct trajectory is a vertical straight line.

$A$ pendulum bob is swinging in a vertical plane such that its angular amplitude is less than $90^o$. At its highest point,the string is cut. Which trajectory is possible for the bob afterwards?
