Question

What are the differences between Pascal's law and Archimedes' principle. (2 points)

Answer 1

Answer:

Archimedes' principle states that when a body is partially or fully dipped into a fluid at rest, the fluid exerts an upward force of buoyancy equal to the weight of displaced fluid.

While understanding this principle few important words we should pay attention to are, 'fluid at rest' & 'weight of displaced fluid'.

Floatation works on the same principle. When a solid body is dipped into a fluid, the fluid exerts an upward force of buoyancy on the solid. If the force of buoyancy equals the weight of the solid, the solid will remain in equilibrium. This is called floatation.

Edit: Just as the weight of a body acts through its centre of gravity, Buoyant force acts through the centre of buoyancy (which is nothing but the centre of gravity of the displaced fluid)
