We are given the permittivity ##\epsilon## of the gas, which should (?) be good enough, as permittivities are based on the polar nature of the dielectric. This is the reason I attempted to use the Helmholtz Free Energy ##F## and use it to try to calculate the electromagnetic component of the...

However, if we were to include the gas particle polarizations in the internal energy, ##∆Q## would clearly not be zero. Was my orginal attempt correct when assuming the gas particles are affected by the electric field ? As the problem does not explicitly mention to ignore the gas polarization...

Firstly, thanks for the response ! And apologies for the use of ##V## for both the variables and lack of LaTeX, as this was posted in a hurry. One query I had, so we do not need to count in the capacitance energy as part of ##U## ? That was the largest source of confusion for me as the energy...

What I'm able to do so far : The magnitude of the charge on the plates as a function of length L and ε should be Q=CV_0=A_0ε/L × V_0 = A_0 V_0 ε / L So the force on the top plate should be F_elec = QE = A_0 V_0² ε / 2 L² So for the process to proceed quasi statically, the force due to pressure...
