Q. 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 the front side
C) Lower in the rear side
D) Lower in the upper side
Explanation
(b) Pressure will be less in front portion of the compartment because in accelerated frame molecules will feel pseudo force in backward direction. Also density of gas will be more in the back portion
