Question

The cubical container $ABCDEFGH$ which is completely filled with an ideal (nonviscous and incompressible) fluid, moves in a gravity free space with a accelaration of $a=a_0(\hat{i}-\hat{j}+\hat{k})$ where $a_0$ is a positive constant. Then the only point in the container shown in the figure where pressure is maximum, is

• A. $H$
• B. $B$
• C. $E$
• D. $F$

Answer 1

Answer: (B)

$B$

$a=a_0(\hat{i}-\hat{j}+\hat{k})$

As there is no gravity, the pressure difference will be only due to the acceleration. So there is only point 'H' is acted upon by a maximum pseudo force. Hence, at point 'H' pressure developed is maximum.

Hence option 'A' is correct.
