One end of massless inextensible string of length `l` is fixed and other end is tied to a small ball of mass `m`. The ball is performing a circular motion in vertical plane. At the lowest position, speed of ball is `sqrt(20gl)`. Neglect any other forces on the ball except tension and gravitational force. Acceleration due to gravity is `g`. At the highest position of ball, tangential acceleration of ball is `-`

Answer» Correct Answer - A
At the highest position of ball, tangential acceleration of ball is zero.
