Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : The drag coefficient of a potato cube falling through air column is more than that of the spherical-shaped one.
Reason (R) : For a sphere which has a continuous geometry, the flow separation points are dependent on Reynolds number
(Re), whereas for a cube, the leading edges are fixed points of separation while reattachment depends on Re
In light of the above statements, choose the correct answer from the options given below.
