Applications of Bernoulli's Theorem

Two light balls are suspended as shown in figure. When a stream of air passes through the space between them, the distance between the balls will

Figure

Show answer and solution

Answer: (d)

  1. Air blown between the balls moves fast there, so by Bernoulli's principle the pressure between them drops.
  2. The still air outside is at higher pressure and pushes the balls inward.
  3. So the answer is (d) decrease.
