Response to the following problem:
steel ball of mass 109 is placed in the tube of cross-sectional area 1cm2 in R chhardt's apparatus. The tube is connected to a jar of air having a capacity of 5 liters, the pressure of the air being 76 em Hg.
(a) What is the period of vibration for the ball?
(b) If the ball is held initially at a position where the air pressure is exactly atmospheric and then allowed to fall, how far will the ball drop before it starts to come up?
