Question

Q.A CLOSED COMPARTMENT CONTAINING GAS IS MOVING WITH SOME ACCELERATION IN HORIZONTAL DIRECTION.NEGLECT EFFECT OF GRAVITY. THEN PRESSURE IN THE COMPARTMENT IS

Answer 1

$\huge{\bold{\red{(B) Less\: in\: front}}}$

The Pressure on the Rear side would be more due to Fictitious force on the rear face. Consequently the pressure on the front side would be lowered.

Fictitious Force acts in the opposite direction of Acceleration.

Answer 2

The pressure will be lower in the front side of the compartment.

Explanation:

• As the gas particle are freely suspended in a compartment.

• Due to inertia the molecules will be pushed back to the compartment.

• Therefore the gas density will be higher in the back region as compared to the front region of the compartment.

• Thus the collision among gas molecules will also increase.

• So the pressure exerted by molecules will be more in the back end of the compartment than the front side of the container.

Thus we can say that the pressure will be lower in the front side of the compartment.
