A cylinder is fill ed with a liquid of density p upto a height h. What is the hydrostatic pressure exerted by the liquid on the bottom of the cylinder, if the cylinder is kept in a lifi moving upwa rds with an acceleration a ?

A

`rhogh`

B

`rho(g+a)`

C

`rho(g-a)`

D

`(rhogh)/(a)`

Text Solution

Verified by Experts

The correct Answer is:
C
For a cylinder at rest, hydrostatic pressure P`=rhogh` But when it is kept in a lift moving upwards, with an acceleration 'a', the effective acceleration becomes
g'=g+a
`:.` Hydrostatic pressure becomes
`P'=rhohg'=rhoh(g+a)`
