Question

Consider the situation of the previous problem. Let the water push the left wall by a force F₁ and the right wall by a force F₂. 

(a) F₁= F₂.  

(b) F₁ > F₂. 

(c) F₁ < F₂.  

(d) The information is insufficient to know the relation between F₁ and F₂.

Answer 1

The correct answer is (b) F₁ > F₂. 

EXPLANATION:  

As the pressure depends on the depth of the liquid at rest, similarly in an accelerating liquid the pressure due to acceleration depends on the horizontal length from the leading surface.
