I came across the following question
- A partially filled oil tanker is being carried on a truck moving with constant-horizontal acceleration. What will happen to the level of oil?
which had the following answer:
-The level of oil will rise on the back side of the tank and fall on the front side
Why does this happen?
When in equilibrium, the back face and the front face of the container applies equal force to the oil. Since the oil is accelerating forward, the back of the container must push the oil harder. And as an adjustment ,the height of the oil rises towards the back to balance this extra force.
