A tanker filled with water up to ⅔ of its height is moving with a uniform speed. On sudden application of brakes, what will be the direction of motion of water in tank? Explain.
Answers
the motion will be in forward direction because the lower water is in contact with the truck . when the truck moves , water also moves but the upper water remains in rest . so , due to the inertia of rest , the water moves in forward direction
Answer:
he correct answer is the option b - Moves forward.
This may be due to inertia. All objects in a system are in the same state of motion.
So, when a tanker is filled with water up to 2/3rd level, the water inside the tanker is at the same velocity as that of the tanker. So, it stays steady. However, when the tanker's brakes are applied, the velocity of the tanker becomes less but there is no external force acting directly on the water. So, the velocity of the tanker decreases but the velocity of the water inside remains as before. So, the water tends to push itself forward towards the wall of the tanker.
