Question
(i) The cubical container ABCDEFGH which is completely filled with an ideal (non viscous and incompressible) fluid, moves in a gravity free space with a acceleration of
a = a0 (î − ĵ +
)
where a0 is a positive constant. Then the only point in the container shown in the figure where pressure is maximum, is
a = a0 (î − ĵ +
)where a0 is a positive constant. Then the only point in the container shown in the figure where pressure is maximum, is
Options
A.B
B.C
C.E
D.F
Solution
a = a0 (î − ĵ 
)
As there is no gravity; the pressure difference will be only due to the acceleration.
At point B the pseudo force is maximum hence pressure is maximum.
At point H the pseudo force is minimum hence pressure is minimum
