Problem
Air flows faster over the upper surface of an aircraft wing than over its lower surface. Which statement best describes the resulting effect on the wing?
(a) Pressure on the upper surface becomes greater, producing a downward force.
(b) Pressure on the lower surface becomes greater, producing an upward force.
(c) Pressure on the upper surface becomes less, producing a downward force on the wing.
(d) Pressure on the lower surface becomes less, reducing any lift produced.
