Given:
A tanker is filled with water upto ⅔ of its height and moving with uniform velocity. Suddenly the brakes are applied.
To find:
Direction of motion of water in the tank.
Concept:
Whenever any object is in a non inertial reference frame it experiences a force known as pseudo force which is directed opposite to the applied force.
Since the water (in the tanker) was present at the time of retardation of the tank , it experienced a pseudo-force .
Retardation force (brake) is the applied force in this case and directed backwards. So , the pseudo-force experienced by the water will be in the opposite direction i.e. in the forward direction.
So final answer:
Water in the tanker will move forward.
