1. The problem statement, all variables and given/known data The charge on the 3.00 cm2 area plates of an air-filled parallel plate capacitor is such that the electric field is at the breakdown value. By what factor will the maximum charge on the plates increase when bakelite is inserted between the plates? (The dielectric strength of air is 3.00 ✕ 106 V/m and that of bakelite is 2.40 ✕ 107 V/m. The dielectric constant of bakelite is 4.90.) 2. Relevant equations C=Q/V C=kC0 C0=ε0A/d V=Ed 3. The attempt at a solution I'm not sure what to do here. I don't even have a strategy to tackle this problem. So far I've tried manipulating all the equations I can find that have to do with capacitors, but it hasn't gotten me anywhere.
