Question:

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

Options :

(a) Remains the same because 500 ms-1 is very much smaller than Vrms 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 (Vrms^2 + (500)^2)/ Vrms where Vrms was the original mean square velocity of the gas
(d)Will be different on the top wall and bottom wall of the vessel

Answer :

(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
