Question

The three tanks above are filled with water to the same depth. The tanks are of equal height. Tank C has the middle surface area at the bottom, tank A the greatest and tank B the least. For each of the following statements, select the correct option from the pull-down menu. (True, False, Less than, Greater Than, Equal)

_______ The pressure exerted on the bottom of tank B is equal than for the other two tanks.

_______ The force exerted by the water on the bottom of tank B is .... the force exerted by the water on the bottom of tank C.

_______ The pressure at the bottom of tank A is .... the pressure at the bottom of tank C.

_______ The force due to the water on the bottom of tank C is .... the weight of the water in the tank.

_______ The water in tank A exerts a downward force on the sides of the tank.

Explanation / Answer

True. The pressure exerted on the bottom of tank B is equal than for the other two tanks.

as the pressure , P = density * g* d

and depth ,d is same for all the tanks.

The force exerted by the water on the bottom of tank B is less than the force exerted by the water on the bottom of tank C.

as the pressure is same for all ,

and the area in B is less than area of V

_______ The pressure at the bottom of tank A is equal to the pressure at the bottom of tank C.

same as A

_______ The force due to the water on the bottom of tank C is equal to the weight of the water in the tank.

True , as there is no force due to walls of container

False , The water in tank A exerts a downward force on the sides of the tank.

the force on walls is sideways .
