Question

An air chamber of volume V has a neck area of cross-section ‘a’ into which a ball of mass m can move up and down without friction. If the ball is press down a little and released then find the time period of oscillation of ball. Here air is ideal & its temperature remains constant & the isothermal. Bulk modulus of air is B.

  1. T equals 2 pi square root of fraction numerator 2 V m over denominator B a to the power of 2 end exponent end fraction end root    
  2. T equals 2 pi square root of fraction numerator V m over denominator B a to the power of 2 end exponent end fraction end root    
  3. T equals 2 pi square root of fraction numerator V m over denominator 2 B a to the power of 2 end exponent end fraction end root    
  4. none    

The correct answer is: T equals 2 pi square root of fraction numerator V m over denominator B a to the power of 2 end exponent end fraction end root
