Question

Two balloons were suspended from a string with a gap of 30 cm between them. A child blows air between the balloons to make them move. He notices that the balloons instead of moving apart moved close together. Why do the balloons move close together?​

Answer 1

❍ Answer :--

When we blow air in between the balloons the air speed in between the balloons increases.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.
