A parallel plate capacitor of plate area A and plate separation d is filled with three dielectric slabs of dielectric constants 3K, K and 2K respectively. Their areas and thicknesses are (A/2, d), (A/2, 2d/3) and (A/2, d/3) respectively. If C0 and C are the capacitances of the capacitor without slabs and with slabs respectively, then the ratio C/C0 is:
- 1(21/10)K✓
- 2(19/10)K
- 3(17/10)K
- 4(13/10)K
Correct answer
(21/10)K
