Answer in units of m.J. 004 10.0 points Which of the following capacitors, each of which has plates of area A, would store the most charge on the top plate for a given po- tential difference VY 1. d/2 Glass T 2. acuum3. d/2 Vacuum T 4. Glass 5. d/2 Air T 005 10.0 points When a certain air-filled parallel-plate ca- pacitor is connected across a battery, it ac- quires a charge (on each plate) of magnitude 207 ,C. While the battery connection is maintained, a dielectric slab is inserted into the space between the capacitor plates and completely fills this region. This results in the accumulation of an additional charge of 292 aC on each plate. K K What is the dielectric constant of the slab? 006 (part 1 of 2) 10.0 points A certain dielectric, with a dielectric con- stant 22, can withstand an electric field of 3 x 10 V/m. Suppose we want to use this di- electric to construct a 0.3 /F capacitor that can withstand a potential difference of 2100 V.
