A vertical cylinder containing helium gas is filled with a piston of \(50 \mathrm{~kg}\) mass and crosssectional area of \(0.025 \mathrm{~m}^{2}\). If the atmospheric pressure outside the cylinder is \(95 \mathrm{kPa}\) and the local gravitational acceleration is \(9.79 \mathrm{~m} / \mathrm{s}^{2}\), then the helium pressure is

(a) \(114580 \mathrm{~Pa}\)

(b) \(3479 \mathrm{~Pa}\)

(c) \(25432 \mathrm{~Pa}\)

(d) \(12008 \mathrm{~Pa}\)
