The following item consist of two statements, one labeled as ‘Assertion A’ and
the other labeled as ‘Reason R’. You are to examine these two statements carefully and decide
if the Assertion A and the Reason R are individually true and if so, whether the Reason is a
correct explanation of the Assertion. Select your answers to these items using the codes
given below and mark your answer sheet accordingly.
(a) Both A and R are true and R is the correct explanation of A
(b) Both A and R are true but R is NOT the correct explanation of A
(c) A is true but R is false
(d) A is false but R is true
Assertion (A) : A body with large curvature causes a larger pressure drag and therefore,
larger resistance to motion.
Reason (R) : Large curvature diverges the streamlines, decreases the velocity resulting in
the increase in pressure and development of adverse pressure gradient
leading to reverse flow near the boundary.
