Question 1, chap 26, sect 3. part 1 of 1 10 points A capacitor is constructed from two metal plates. The bottom portion is filled with air and the top portion is filled with material of dielectric constant . The plate area in the top region is the same as that in the bottom region. Neglect edge effects. E Determine the ratio U t U b of energy stored in the top portion to the bottom portion. 1. U t U b = + 1 2. U t U b = 3. U t U b = 2 4. U t U b = 1 5. U t U b = 1 2 6. U t U b = 2 + 1 7. U t U b = 1 2 8. U t U b = 1 + 1 9. U t U b = 1 2 + 1 10. U t U b = 2 Question 2, chap 26, sect 3. part 1 of 2 10 points A capacitor is constructed from two square metal plates. The gap between the plates is filled with two dielectrics of equal size as shown in the figure below. Neglect edge ef- fects.fects....
