- Homework Statement
- A cube-shaped tank is filled with water and attached firmly to a cart moving with an acceleration of 20 cm/s^2. Find the pressure at a point which is 10 cm deep and 10 cm from the wall of the tank.

- Relevant Equations
- Hydrostatic pressure

I draw this diagram:

The formula for hydrostatic pressure is: ##P=\rho g h## so I just plug everything

$$P=1000 \times 9.8 \times 0.1=980 Pa$$

Will the acceleration of the cart affect the hydrostatic pressure?

Another thing that came to my mind was there would be extra force coming from normal force between water and left and right side of the tank and since the tank is accelerated to the right, normal force from the left part of the tank is bigger than the right part causing net force to the right.

But I am not sure whether I need to consider this to answer this question and how to proceed.

Thanks
