Q1: The depth of the centre of pressure on a vertical rectangular gate (4 m wide, 3 m high) with water upto top surface, is

ANS:C - 2.0 m

Apologies for the confusion. Let's reconsider the calculation. The depth of the center of pressure on a vertical rectangular gate submerged in water can be calculated using the formula: Depth of center of pressure=ℎ/2​ Where ℎh is the depth of the water above the gate. In this case, the water depth is h=3 meters (since the gate is fully submerged). Substituting the value: Depth of center of pressure=3/2=1.5 meters Thus, the correct depth of the center of pressure should be 1.5 meters, not 2.0 meters. Thank you for your patience.
