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

A

increase

B

decrease

C

remain the same

D

may increase or decrease depending on the speed of air

Text Solution

Verified by Experts

The correct Answer is:
B
When the speed of the air between the balls increases, then according to Bernoulli.s theoram, the pressure in this region decreases. Therefore, the balls will be pushed towards each other by the air pressure in the outer region.
