A cylindrical vessel containing a liquid is closed by a smooth piston of mass m as shown in the figure. The area of cross section of the piston is A. If the atmospheric pressure is `P_0`, find the pressure of the liquid just below the piston.
,

A

`P_0`

B

`P_0 +(mg)/(A)`

C

`(mg)/(A)`

D

Data is not sufficient.

Text Solution

Verified by Experts

The correct Answer is:
B
(b) since the piston is in aquarium,, `:. PA = P_0 A + mg or P = P_0 + (mg)/(A)`
