A cylindrical tank contains water up to ...

A cylindrical tank contains water up to a height H. If the tank is accelerated upwards with acceleration a, the pressure at the A is `p_(1)`. If the tank is accelerated downwards with acceleration a the pressure at A is `p_(2)`. Then

A

`p_(1) lt p_(2)`

B

`p_(1)=p_(2)`

C

`p_(1) gt p_(2)`

D

Data insufficient

Text Solution

Verified by Experts

The correct Answer is:
C
When moving upwards `(dp)/(dh)=-rho(g+a)" and when moving downwards "(dp)/(dh)=-rho(g-a)`
In first case, pressure decreases with h more repidly.
