Solution

Dear student,
Find the answer to your query as under:

When there is a pressure difference between two points then it means that due to the pressure gradient present there exists a net force in the direction from the area of higher pressure towards the lower pressure. So when an airplane flies there is a net high-pressure region generated beneath wings and a low-pressure area above the wings, thus a net force from below acts on the wings which provides the necessary lift for the plane to get in the air.
