Question 53
Easy

Figure 1 shows two horizontal concrete platforms, A and B, resting at the bottom of a deep diving pool.

Both platforms have the same height, meaning their top surfaces are at the exact same depth below the water surface.

The area of the top surface of platform B is 3 times larger than the top surface area of platform A.

Figure 1: Platforms A and B at the bottom of a diving pool

What is the pressure due to the water on the top surface of platform B?

one third of the pressure on platform A

the same as the pressure on platform A

three times the pressure on platform A

nine times the pressure on platform A
