Question

Derivation of effect of gravity on Pascals law and also explain Pasclas law.

Answer 1

Hey mate Bonjour here is your answer :

Pascals Law = According to Pasclas law effect of gravity is neglected the pressure at every point of liquid will be in equilibrium of rest .

Derivation of effect of Pascals law is in image :

Answer 2

The fact that g appears explicitly in Pascal's law tells you the answer. Setting g→0 in a limiting procedure is identical to taking Δh→0 (or ρ→0).

So Pascal's law reduces in these (equivalent) limits as the rather trivial statement that ΔP=0.
