Questions
A rectangular parallel-plate capacitor has a dielectric slab that partially fills the space between the plates as shown in fig. The energy of the capacitor with charge q is
detailed solution
Correct option is A
C=ε0bxS+Kε0b(a−x)S=ε0bS[x+K(a−x)]=ε0bS[Ka−(K−1)x]∴U=12q2C=q2S2ε0b1[Ka−(K−1)x]Talk to our academic expert!
