Question

A closed rectangular tank is completely filled with water and is accelerated horizontally with an acceleration $a$ towards right as shown in figure. Then pressure is maximum and minimum (respectively) at:

• A. $B$ and $D$
• B. $C$ and $D$
• C. $B$ and $C$
• D. $B$ and $A$

Answer 1

The correct option is A $B$ and $D$

Due to acceleration towards right, the pressure will increase in leftward direction (pressure increases in a direction opposite to that of acceleration of container).
$\Rightarrow P_A>P_D\&P_B>P_C...\left(i\right)$


Similarly due to height difference of liquid column, pressure in liquid will be increase in vertically downward direction.
$\Rightarrow P_B>P_A\&P_C>P_D...\left(ii\right)$

On comparing relations $\left(i\right)$ and $\left(ii\right)$, we conclude that pressure is maximum at point $B$ and pressure is minimum at point $D$.
$\therefore$Option $\left(a\right)$ is correct.
