# Pascal law of fluids

## Homework Statement

a water filled symetrical container has four pistons , one on each side of area A to keep water in equilibrium

Now an additional force F is applied to all four pistons . then increase in pressure at the middle of container will be:

## Homework Equations

pascal law: change is pressure is transmitted to whole fluid

## The Attempt at a Solution

since F is applied from four sides so pressure should have been 4F/A but the solution says F/A

What's the definition of pressure?

Perpendicular force per unit area..

Now apply that definition to the problem.

but the force is from all sides so either vector sum should be 0
or if add as scalar it should be 4F/A...
but the answer is only F/A

The force is being applied to a fluid, not a solid. What happens when you stand on a water balloon?

can you give a more detailed reply to this question....
