A cubic vessel (with face horizontal + vertical ) contains an ideal gas at NTP. The vessel is being carried by a rocket which is moving at a speed of `500 ms^(-1)` in vertical direction. The pressure of the gas inside the vessel as observed by us on the ground.

A

remains the same because 500 m/s is very much smaller than `v_(rms)` of the gas

B

remains the same because motion of the vessel as a whole does not affect the relative motion of the gas molecules and the walls

C

will increase by a factor equal to `[v_(rms)^(2)+(500)^(2)]//v_(rms)^(2),"where"v_(rms)` was the original mean square velocity of the gas

D

will be different on the top wall and bottom wall of the vessel.

Text Solution

Verified by Experts

The correct Answer is:
B
As `P=(nRT)/(V)'` it (i.e., P) remains unaffected as n.R.T and V.
