when air is blown between two balls suspended close to each other, they are attracted towards each othe. why ?
Answers
hlo mate your answer
When we blow air in between the balloons the air speed in between the balloons increases. This causes a low pressure region between the balloons. As the air pressure outside this region is high, the air will push the balloons to the low pressure region. So the balloons will come closer.
Assuming your query is about balloons. Anyway, the answer is same for balls of small masses also. But if the balls are not too light, we need to blow air with the help of other machines to observe this effect.
Hey mate,
Actually,
it's because of bernouill's theorem.
=> Ans. When air is blown in between two balls suspended close to each other with high speed, a low pressure is created between the balls which is much less than the atmospheric pressure beyond the balls. Due to this, balls are attracted towards each other. This is according to Bernoulli’s theorem.
Hope it will help you
