A gas is enclosed in a vessel of volume `V` at a pressure `P`. It is being pumped out of the vessel by mean of a piston-pump with a stroke volume. `v`. What is the final pressure in the vessel after `'n'` strokes of the pump ? Assume temperature reamains constant.

A

`P ((V)/(V+ v))^(n)`

B

`(PV)/((V-v)^(n))`

C

`P(V^(n))/(V^(n))`

D

`P((V)/(V-v))^(n)`
