JEE Main 8 April 2026, Shift 2, Physics Q33

Question 33 of 75 in this shift, Physics question 8 of 25, Section A.

A liquid of density 600 kg/m3^3 flowing steadily in a tube of varying cross-section. The cross-section at a point AA is 1.0 cm2^2 and that at BB is 20 mm2^2. Both the points AA and BB are in same horizontal plane, the speed of the liquid at AA is 10 cm/s. The difference in pressures at AA and BB points is ________ Pa.
