In the case that it is being discharged, would you need to let ##I = -\frac{dQ}{dt}##, instead of ##I = \frac{dQ}{dt}##? Also what do you do if you do not know whether it is being charged or discharged? Would assuming the sign always give you the right answer? Would you just get a negative Q in...

Wonderful! Thank you all so much for your help :)

Hi! Thank you all for your reply, I'm still having trouble seeing how using the below setup (focusing on the Gaussian surface S1) can reveal the total magnitude of the electric force between the plates, ##\frac{\sigma}{\epsilon_0}##. Wouldn't you get the same result...

I'm using a cylindrical gaussian surface that is right inside the positively charged conducting plate and has the other end in-between both plates. I'm having trouble discerning whether the charge density(##q_{in}##) should be ##\frac{\sigma}{2 \epsilon_0}## since the cylinder is only...
