Pressure exerted by a liquid is due to its:

1. weight
2. mass
3. volume
4. area

A body weighing 5 kgf, placed on a surface of area 0.1 m², exerts a thrust on the surface equal to:

1. 50 kgf
2. 5 kgf
3. 50 kgf m^-2
4. 5 kgf m^-2

Pressure inside a liquid increases with:

1. increase in depth.
2. decrease in depth.
3. decrease in density.
4. none of the above.

The pressure and thrust are related as:

1. Pressure = Thrust
2. Pressure = Thrust x Area
3. Pressure = $\dfrac{\text{Thrust}}{\text{Area}}$
4. Pressure = $\dfrac{\text{Area}}{\text{Thrust}}$
