Physics Question on mechanical properties of fluid
Air is blown .between .two suspended balls. Then
A
Positions of balls remain the same
B
Balls move towards each other
C
Balls move away from one another
D
Balls start spinning
Answer
Balls move towards each other
Explanation
Solution
According to Bernoulli's principle if air is blown between two suspended balls the air pressure between them decreases but pressure at the outside points remain same. So there is pressure difference across both the balls. So they move towards each other.
