A flat plate is moving normal to its plane through a gas under the reaction 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?

The pressure difference between the leading and trailing faces of the plate is proportional to uv

The resistive force experimenced by the plate is proportional to $$v$$

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

At a later time the external force $$F$$ balances the resistive force
