For a finite wing and an infinite wing (airfoil), zero lift angle of attack is zero.

For a finite wing and an infinite wing (airfoil), zero lift angle of attack is zero. Correct Answer True

When the lift is zero, there are no induced effects i.e. induced drag and induced angle of attack are zero. Also, since the induced angle of attack is zero, the geometric angle of attack is the same as the effective angle of attack. This means zero lift angle of attack is the same for wing and airfoil.
