A flat plate is moving normal to its plane through a gas under the action of a 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 pressure difference between the leading and trailing faces of the plate is proportional to uv
(B) The resistive force experienced by the plate is proportional to v
(C) The plate will continue to move with constant nonzero acceleration, at all times
(D) At a later time the external force F balances the resistive force
