A Large Water Storage Container Is Filled to a Depth

Multiple Choice

A large water storage container is filled to a depth of 3.0 m.The volume above the water is filled with air.In order to pump the water from the container,the air pressure in the container is increased by 3.0
10⁵ N/m².What happens to the pressure in the water at a depth of 1.0 m when the air pressure is increased?

A) Nothing,it is still at a depth of 1.0 m and the pressure in the water depends only on the depth.
B) It increases by 1.0 10⁵ N/m²,since it is at 1/3 the depth of the water.
C) It increases by 2.0 10⁵ N/m²,since it is at 2/3 the depth from the bottom of the container.
D) It increases by 3.0 10⁵ N/m².
E) It increases by 3.0 10⁵ N/m² + 9.8 10³ N/m² since it is 1.0 m deep in the water.
