Understanding Pascal's law

1. 1. A liquid is filled in a large cylindrical container. The pressure exerted by the liquid on the wall of the container depends on :

• Density of the liquid

• Depth of the liquid

• Gravity

• All of the above

2. 2. Pressure is a scalar quantity, because...

• it is the ratio of force to area and both force and area are vectors

• it is the ratio of the magnitude of the force to area

• it is the ratio of the component of the force normal to the area

• it does not depend on the size of the area chosen

3. 3. According to _____, the intensity of pressure in a liquid at rest is constant in all directions.

4. 4. As per Pascal's law :

• intensity of pressure at a point in a moving fluid is equal in the direction of the applied force

• intensity of pressure at a point in a static fluid is equal in all directions

• intensity of pressure at a point in a moving fluid is equal in all directions

• intensity of pressure at a point in a static fluid is equal in the direction of applied force

5. 5. The decrease in pressure takes place when....

• the force is increased but not the area

• the area is decreased but not the force

• either force increases or area decreases

• the area increases and the force decreases

6. 6. Pascal's law is valid only for ____ .

• metals

• water

• solids

• fluids

State the main limitation which is common among hydraulic lift and pneumatic system.
