By Pascal’s law, pressure is equally transmitted to enclosed water in all directions. Statement II directly reflects this. Statement I is also true because at a given depth (level) in a static fluid, the pressure is the same in all directions. This is due to the hydrostatic pressure which depends only on the density of the fluid and depth.

In the first configuration (1) as shown in the figure, four identical charges \( q_0 \) are kept at the corners A, B, C and D of square of side length \( a \). In the second configuration (2), the same charges are shifted to mid points C, E, H, and F of the square. If \( K = \frac{1}{4\pi \epsilon_0} \), the difference between the potential energies of configuration (2) and (1) is given by:
