(a) At the extreme position, the speed of the bob is zero. If the string is cut, it will fall vertically downwards.
(b) At the mean position, the bob has a horizontal velocity. If the string is cut, it will fall along a parabolic path.
(b) At the mean position, the bob has a horizontal velocity. If the string is cut, it will fall along a parabolic path.
