Water level problem

This is the solution to the water level problem discussed in my blog ankit-mathur.blogspot.in (alternatively ankitmathur.in).

The box is accelerating in the direction BA, creating a pressure differential between two ends of the box. Since the acceleration is constant, the ratio of pressure at the front and rear end of the box is constant, and so is the ratio between the heights in the tubes.

In simpler words, if the box is accelerating in direction BA then there is a pseudo force acting on the water in the direction AB, which is pushing water in B tube higher.
