Question
A water tank filled with water to half its capacity is kept on a truck that is moving with constant velocity in the North direction. The driver applies a sudden break, the water in the tank would ____.
- Spill all over
- Spill forward
- Spill backward
- Stay still
Hint:
Due to inertia of water it would have a tendency to continue in its forward motion.
The correct answer is: Spill forward
- As the truck is moving forward with a constant velocity, the tank along with the water is also moving under constant velocity.
- When a sudden brake is applied, it tends to oppose the forward motion of water in the tank.
- Due to the inertia of water, it would have a tendency to continue its forward motion. Hence on sudden braking, it suddenly moves forward.
