(a) 22.9 N/cm^2

(b) 45.8 N/cm^2

(c) 11.5 N/cm^2

(d) None of the mentioned

This question was posed to me during an online interview.

This is a very interesting question from Horizontal and Inclined Plane Surface Submerged in a Liquid topic in portion Hydrostatic Forces on Surfaces of Fluid Mechanics

The correct option is (a) 22.9 N/cm^2

Easy explanation: Total pressure, F=w*a*y

                                                 =9.81*650*6*2*3

                                                 =22.9 N/cm^2.
