Assertion (A): In free cylindrical vortex about a vertical axis, pressure increases with distance from axis and this increase is proportional to square of the radial distance.
Reason (R): Tangential velocity is inversely proportional to radial distance and energy of fluid element is conserved in a free cylindrical vortex.
(A) Both A and R are individually true and R is the correct explanation of A
(B) Both A and R are individually 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
