Consider the equations

$P = \underset{Δ S \to 0}{L i m} \frac{F}{Δ S}$ and $P_{1} - P_{2} = ρ g z$

In an elevator accelerating upward,

Options:

Answer:

Solution:

Equation 1 is universal equation of pressure but the second equation is valid only when it is in state of rest, while moving upward the pressure difference is $Δ P = z ρ (g + a)$
