1. The problem statement, all variables and given/known data A square parallel plate capacitor with vertical plates of area A and distance d, charged with a constant charge Q and is completely filled with a dielectric material the same dimension as the gap between the plates, with dielectric constant k and mass m. Assuming the dielectric is a solid block of material that can move inside the capacitor with no friction, what would be the equilibrium condition in the presence of gravitational field? What would be the period of small oscillations around this equilibrium point? 2. Relevant equations C=(k[tex]\epsilon[/tex]0A)/d 3. The attempt at a solution Honestly I dont know where to begin with this question. Is it suggesting that the dielectric would oscillate from side to side between the plates? How? Im assuming ive just stared at the problem too long and im missing something obvious, so if someone could just nudge me in the right direction by pointing out what this question is asking it would help a lot.
