Question

The pressure on the top surface of an
aeroplane wing was 0.90 x 105 Pa and
at the bottom surface is 0.91 x 106 Pa.
If the area of each surface is
40 m², the net lift force on the wing
is
(in 104 N)​

Answer 1

Explanation:

Difference in pressure of top and bottom surface =500Pa

Area =50m2

So, Dynamic lift =pressure difference ×Area

                           =5000×50N

                           =25×104N

Answer 2

Answer:

If the area of each surface is 50m^2 , the dynamic lift on the wing is. ... Difference in pressure of top and bottom surface =500Pa. Area =50m2. So, Dynamic lift =pressure differe nce ×Area

pls mark me brain list

hope it will help you
