Homework Statement
A Glass of water is freely sliding down an inclined plane. The water surface has settled down after some initial disturbances. Which of the three cases is possible for the shape of the water surface:
1) It will remain parallel to the incline
2) The water surface will rise towards the direction of the acceleration parallel to incline
3) The water surface will rise away from the direction of acceleration parallel to incline.
The Attempt at a Solution
I think the answer is 3. It is because the water will experience a pseudo accln. away from the direction of the actual accln. parallel to the incline and another normal force acting on it perpendicular to incline. The resultant of this will produce a force that will cause the liquid surface to bend like it is stated in no. 3 as the liquid surface is always perpendicular to the force applied. But somebody said the answer is 1. So I'm not sure. ( N. B. I do not know the correct answer)
