Question:
A vessel containing a liquid of density \( d \) moves down with an acceleration \( a \,(a < g) \). The pressure due to the liquid at a depth \( h \) below the free surface of the liquid is
A vessel containing a liquid of density \( d \) moves down with an acceleration \( a \,(a < g) \). The pressure due to the liquid at a depth \( h \) below the free surface of the liquid is
Show Hint
In accelerating frames, replace \( g \) with effective gravity.

- \( hgd \)
- \( h(g-a)d \)
- \( h(g+a)d \)
- \( h\left(\frac{g}{a}\right)d \)
- \( h\left(\frac{a}{g}\right)d \)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Effective gravity:
\[
g_{eff} = g - a
\]
Step 1: Pressure formula.
\[ P = d g_{eff} h \] \[ = d(g-a)h \]
Step 1: Pressure formula.
\[ P = d g_{eff} h \] \[ = d(g-a)h \]
