Vedclass · Answer

(D) The lift force on an aeroplane wing is explained by Bernoulli's principle. Due to the shape of the wing (aerofoil),the air speed over the upper surface is greater than the air speed over the lower surface. According to Bernoulli's theorem,where the speed of the fluid is higher,the pressure is lower. Thus,the pressure on the upper surface is lower than the pressure on the lower surface. This pressure difference creates an upward force called lift,which balances the weight of the aeroplane.

The weight of an aeroplane flying in the air is balanced by:
