Consider a mixture of gas molecule of types $A, B$ and $C$ having masses $m_{A}\,<\,m_{B}\,<\,m_{C}$ ratio of their root mean square speeds at normal temperature and pressure is :
  • A${v}_{A}={v}_{{B}} \neq {v_C}$
  • B$\frac{1}{v_{A}}\,>\,\frac{1}{v_{B}}\,>\,\frac{1}{v_{c}}$
  • C${v}_{{A}}={v}_{{B}}={v_C}=0$
  • D$\frac{1}{v_{A}}\,<\,\frac{1}{v_{B}}\,<\,\frac{1}{v_{C}}$

    A flat plate is moving normal to its plane through a gas under the action of constant force $F$. The gas is kept at a very low pressure. The speed of the plate $v$ is much less than the average speed $u$ of the gas molecules. Which of the following options is/are true?

    [$A$] The resistive force experienced by the plate is proportional to $\mathrm{v}$

    [$B$] The pressure difference between the leading and trailing faces of the plate is proportional to uv

    [$C$] The plate will continue to move with constant non-zero acceleration, at all times

    [$D$] At a later time the external force $F$ balances the resistive force.
