Would water pressure be the same at the same depth in two containers that had very different shapes? explain.

For any given point in a fluid, the pressure is the same in all directions, even sideways or pointing up. So for two points of equal depth the pressure is the same regardless of the shape of the container above it. This is a characteristic of liquids to take the shape of their container.

Hope this helps! There are videos (I recently watched one for school) about this!

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
