Assertion: A ball tied by thread is undergoing circular motion (of radius R) in a vertical plane. (Thread always remains in vertical plane). The difference of maximum and minimum tension in thread is independent of speed (u) of ball at the lowest position (u>5gR).
Reason: For a ball of mass $m$ tied by thread undergoing vertical circular motion (of radius R ), difference in maximum and minimum magnitude of centripetal acceleration of the ball is independent of speed (u) of ball at the lowest position (u>5gR).
