A cylinder is fitted with a piston, beneath which is a spring, as in the drawing. The cylinder is open at the top. Friction is absent. The spring constant of the spring is 4000 N/m. The piston has a negligible mass and a radius of 0.022 m.

(a) When air beneath the piston is completely pumped out, how much does the atmospheric pressure cause the spring to compress?

(b) How much work does the atmospheric pressure do in compressing the spring?

a. F/ K = x

1.013 x 10^5/ 4000Nm = x


Am I correct so far?

No, that is not correct. The force F is not the pressure, it is the pressure multiplied by the piston area pi r^2.
