The three tanks shown above are filled with water to an equal depth. All the tanks have an equal height. Tank A has the middle surface area at the bottom, tank B the least and tank C the greatest.
(Select T-True, F-False, G-Greater than, L-Less than, E-Equal to. If the first is F the second L and the rest G, enter
FLGGGG).

A) The water in tank C exerts an upward force on the sides of the tank.
B) The pressure exerted on the bottom of tank C is greater than for the other tanks.
C) The force due to the water on the bottom of tank C is ... the weight of the water in the tank.
D) The force exerted by the water on the bottom of tank C is ... the force exerted by the water on the bottom of tank A
E) The pressure at the bottom of tank B is ... the pressure at the bottom of tank C

I can't seem to figure this one out. I've made several attempts and they are all wrong.

Welcome to PF.

What determines pressure?

 

[daisy497]

Pressure = Force/Area
