A 10 cm^3 piece of wood if forced to be fully submerged 2.0 m below the surface of the lake. Which statement below is true? Density of wood is larger than the density of water. A) Buoyant force acting on the wood is less than the weight of the piece of wood. B) The buoyant force acting on wood piece would be larger if this object was submerged 3.0 m below the surface of the lake. C) To know whether buoyant force is larger than the weight, one needs to know the specific value of atmospheric pressure. D) All of these statements are false.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
