Q1: On an inclined plane, centre of pressure is located

ANS:C - below the centroid

On an inclined plane, the center of pressure is located below the centroid. The center of pressure is the point on a submerged or partially submerged surface where the resultant force of the fluid pressure acts. In the case of an inclined plane submerged in a fluid, the center of pressure is below the centroid of the submerged area. This phenomenon occurs because the pressure increases with depth in a fluid, and as a result, the force exerted by the fluid on the inclined surface is greater at deeper points. This causes the center of pressure to be located below the centroid. In summary, the center of pressure on an inclined plane is typically located below the centroid of the submerged area.
