Physics Question on mechanical properties of fluid
A closed compartment containing gas is moving with some acceleration in horizontal direction. Neglect effect of gravity. Then the pressure in the compartment is
A
same everywhere
B
lower in front side
C
lower in rear side
D
lower in upper side
Answer
lower in front side
Explanation
Solution
The pressure on the rear side would be more due to fictitious force (acting in the opposite direction of acceleration ) on the rear face. Consequently, the pressure in the front side would be lowered.
