A container filled up to about 2/3rd's with water moves with a unifrom acceleration of 'a' due to a force 'F'. Considering the fact that the defining property of a fluid requires that it's free surface be normal to the net force acting on it, how can the liquid's free surface make an angle given by tan(theta) = g/a with the horizontal, when it should be completely perpendicular to the horizontal (as this is the direction in which the force is acting).
