Academician A.F. To determine the amplitude of vibration of the tuning fork leg, Ioffe brought a steel ball on a thread to it until the ball came into contact with the leg (figure). What is the amplitude of oscillation A of the tuning fork leg, if the maximum lift of the ball in numerous experiments after one rebound turned out to be equal to H? Frequency of vibration of the tuning fork leg n. The mass of the ball is much less than the mass of the tuning fork.
