[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.

Why?

Given explanation.

Or tank is inclined.

Option C is correct.

Since truck is moving with constant acceleration it is representing Uniform flow situation.

C is correct as the truck is moving in constant horizontal acceleration.

I think there may be inertia concept. As a truck moving in a forward direction inertia will act opposite to it and water level rises on back side.

@All

Given answer is correct:
ax =a and az= 0 then dz/DX = -ax/az+g becomes -ax/az ie opp to the slope of free liquid surface.

For constant velocity the water level same on both sides. But at constant acceleration velocity changes equally per unit time. That push the liquid back.

Option D is correct, because the truck is moving with constant acceleration, and acceleration means rate of change of velocity.
