Concept explainers

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.

Question

A mass suspended on a string is lowered into a beaker of water, which stands on a
scale, as shown.
Im
How does the force on the scale change when the mass is completely submerged
(but not touching the bottom) compared to before the mass entered the water?
The force increases by an amount equal to the weight of the water displaced by
the weight's volume.
The force decreases, because the water above the weight is partially resting on
the weight and is held up by the string, reducing the overall mass on the scale.
The force is unchanged (the mass is suspended by the string!)
The force increases by an amount equal to the full weight of the mass, mg
