The cubical container ABCDEFGH which is completely filled with an ideal (nonviscous and incompressible) fluid, moves in a gravity free space with a acceleration of `a=a_0 (hat i -hatj +hat k)` where `a_0` is a positive constant. Then the minimum pressure at the point will be

A

B

C

C

E

D

H

Text Solution

Verified by Experts

The correct Answer is:
D
`a=a_(0) (hati-hatj+hatk)`
As there is no gravity, the pressure difference will be only due to the acceleration. All points other than point 'B' are acted upon by a pseudo force. Hence, at point 'B' pressure developed is zero.
