Prove that the depth of the centre of pressure of a planearea immersed in a liquid is greater than the depth of itscentre of gravity |
|
Answer» Centre of pressure is the point at which the resultant force of buoyancy acts,while centre of gRavity is the point at which the resultant gravitational acts.(actually at these points the force doesn't acts alone ,but we choose a such point where the effective force can beassumed) Centre of pressure of a body immersed in a fluid depends on thephysical dimensions of The body,(ie. the shape and the volume displaced by the body). So it's dependent on the body you take,thatwhether the Centre of Pressure will lie ABOVE or BELOW the centre of graviTy. |
