Two glass containers, each holding a different liquid, are positioned beside one another. Point P is at a depth $h$ below the liquid surface in one container. Point Q is at a depth $h$ below the liquid surface in the other container. What causes the pressure at P to be different from the pressure at Q?
- AThe atmospheric pressure is different at P.
- BThe densities of the liquids are different.
- CThe gravitational field strength is different at P.
- DThe shapes of the containers are different.
