A pressure gauge is moved downwards in a storage vessel containing liquid fertiliser. The gauge is initially at a depth of 0.80 m. The pressure due to the liquid increases by 14 112 Pa as it is moved. The density of the liquid fertiliser is 1200 kg/m³ and the gravitational field strength is 9.8 N/kg.
What is the final depth of the gauge below the surface?
0.40 m
12.6 m
2.0 m
1.2 m
