Question

A closed compartment containing gas is moving with some acceleration in the horizontal direction. Neglect effect of gravity. Then the pressure in the compartment is

• A. Same everywhere
• B. Lower in front side
• C. Lower in the rear side
• D. Lower in the upper side

Answer 1

The correct option is B

Lower in front side

Step 1 : Given data

All the gas molecules inside a closed compartment gas molecules moving with some acceleration in the horizontal direction

Step 2 : The pressure in the compartment

Here .density of the gas molecules is more on the rear side. The pressure on the rear side is more due to fictitious force acting in the opposite direction of acceleration. So the pressure on the front side would be lowered.

Hence the pressure in the compartment lower on the front side

Therefore the correct answer is Option B
