A submarine is located at a depth of $130\,\text{m}$ beneath the sea surface. The pressure acting on the submarine because of the sea water is $p$. The submarine then moves down to a depth of $260\,\text{m}$ beneath the surface. Assume the density of sea water remains constant. What is the difference between the pressures on the submarine due to the sea water at these two depths?
- A$0$
- B$0.5p$
- C$p$
- D$2p$
