For a finite wing, induced drag increases with an increase in aspect ratio.

(a) False

(b) True

The question was posed to me in class test.

I need to ask this question from Prandtl’s Classical Lifting-Line Theory topic in division Flow over Airfoils over Finite Wing of Aerodynamics

The correct choice is (a) False

Best explanation: The induced drag coefficient for a finite wing is inversely dependent on the aspect ratio. Thus, the induced drag increases with the decrease in aspect ratio and vice versa for a finite wing with the same lift.
