Q1: A water tank partially filled with water is being carried on a truck moving with a constant horizontal acceleration. The level of the water

A rises on the front side of the tank

B falls on the back side of the tank

C remains the same at both sides of the tank

D rises on the back side and falls on the front side

E none of these.

ANS:D - rises on the back side and falls on the front side

When a water tank is being carried on a truck with constant horizontal acceleration, the water inside the tank will experience inertial effects due to the acceleration. This phenomenon is described by the principle of inertia and is known as the "water sloshing" effect. As the truck accelerates forward, the water inside the tank tends to stay in its current state of motion due to inertia. Therefore, the water will slosh backward within the tank, causing the water level to rise at the back side of the tank and fall at the front side. Thus, the correct option is: rises on the back side and falls on the front side.
