Assertion & Reason +4 −1

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.

Both (A) and (R) are true and (R) is the correct explanation of (A) Both (A) and (R) are true but (R) is NOT the correct explanation of (A). (A) is true but (R) is false. (A) is false but (R) is true.
