Answer:
the smallest separation between two objects is 0.8067 m 
Explanation:
 Given the data in the question;
Altitude h = 5.75 km = 5750 m
Diameter D = 4.0 mm = 0.004 m
λ = 460 nm = 4.6 × 10⁻⁷ m
Now, Using Rayleigh criterion for Airy disks resolution.
we know that, Minimum angular separation for resolving two points is;
θ = 1.22λ / D
so we substitute
θ = (1.22 × 4.6 × 10⁻⁷)  / 0.004
θ = 5.612 × 10⁻⁷ / 0.004
θ = 1.403 × 10⁻⁴ rad  
so minimum separation  =  θh
 =  θh
so we substitute
  = (1.403 × 10⁻⁴) × 5750 m
 = (1.403 × 10⁻⁴) × 5750 m
  = 0.8067 m
 = 0.8067 m
Therefore, the smallest separation between two objects is 0.8067 m
