  • A$(V_{rms})_1 < (V_{rms})_2 < (V_{rms})_3$ and ${(\overline K )_1} = {(\overline K )_2} = ({\overline K _3})$
  • B$(V_{rms})_1 = (V_{rms})_2 = (V_{rms})_3$ and ${(\overline K )_1} = {(\overline K )_2} > {(\overline K )_3}$
  • C$(V_{rms})_1 > (V_{rms})_2 > (V_{rms})_3$ and ${(\overline K )_1} < {(\overline K )_2} > ({\overline K _3})$
  • D$(V_{rms})_1 > (V_{rms})_2 > (V_{rms})_3$ and ${(\overline K )_1} < {(\overline K )_2} < {(\overline K )_3}$

    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 $\mathrm{v}$
