The resultant of all normal pressures acts
A. at e.g. of body
B. at center of pressure
C. vertically upwards
D. at metacentre
Answer: Option B
Solution(By Examveda Team)
The resultant of all normal pressures in a fluid acts at the center of pressure. The center of pressure is the point where the total force due to fluid pressure can be considered to act on a submerged surface. It is essential in the analysis of fluid forces on submerged surfaces.Therefore, the correct answer is Option B: at center of pressure.
