An air piston of area \(0.020\ \text{m}^2\) is used to lift a weight of \(150\ \text{N}\). The piston is connected to a vertical tube filled with water (density \(1000\ \text{kg m}^{-3}\)). (a) Calculate the pressure exerted by the piston. (b) Determine the height of a water column that would produce the same pressure. (c) If the tube were instead filled with oil of density \(800\ \text{kg m}^{-3}\), what height of oil would be required to give the same pressure?

Answer Options

A. Pressure = 7.5×10^3 Pa; water column height ≈ 0.87 m; oil column height ≈ 0.96 m
B. Pressure = 7.5×10^2 Pa; water column height ≈ 0.77 m; oil column height ≈ 0.96 m
Correct Answer C. Pressure = 7.5×10^3 Pa; water column height ≈ 0.77 m; oil column height ≈ 0.96 m
D. Pressure = 7.5×10^3 Pa; water column height ≈ 0.77 m; oil column height ≈ 1.20 m
Correct Answer
C
Correct Option:
Pressure = 7.5×10^3 Pa; water column height ≈ 0.77 m; oil column height ≈ 0.96 m
