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.
