(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A plastic cylindrical tube, weight-less, area = 10 cm^2, length = 2m, upper-closed, vertically immersed in mercury, completely filled by mercury.

The upper side is at the same level of mercury, the outer pressure is 760 torr. Calculate the work needed to raise the tube of 1,52 m.

Mercury density: 13595kg/m^3.

2. The attempt at a solution

I have realised that I need to win the weight force and the outer pressure force. My result is: 550 J (I have added weight force work to the outer pressure work).

My book says the result is 116 J.

Can you help me? Who is wrong?

Thank you very much
