3 An air chamber of volume V has a neck of crow sectional area a into which a light ball of mass just fits and can move up and down without friction The diameter of the ball is equal to that of the neck of the chamber The ball is pressed down a little and released If the bulk modulus of air is B the time period of the oscillation of the ball is b T 2n a T 2m Ba mV BV mB ma mV Va Ba A spring balance has a scale that reads from 0 to c T 2 d T 2r
