Question

Pressure at the same level in a water tank is

• A. Equal in all directions
• B. Unequal in all directions
• C. Same at every level
• D. None of these

Answer 1

The correct option is A

Equal in all directions

The pressure at a point = Depth of that point from the surface $\times$Density of fluid $\times$Acceleration due to gravity.

$P=h\rho g$

So the pressure will increase as you increase the depth, density of the liquid and acceleration due to gravity.

And decrease when you decrease the depth, density of the liquid and acceleration due to gravity.

At every point on the same level of liquid, pressure remains the same.
