Both $(a)$ and $(b)$

Vedclass · Answer

(D) When a metallic sheet of thickness $t$ is inserted between the plates of a parallel plate capacitor with plate separation $d$,the new capacitance $C'$ is given by $C' = \frac{\epsilon_0 A}{d - t}$.Since $t > 0$,the denominator $(d - t)$ is less than $d$,which implies that $C' > C$. Thus,the capacitance increases.Furthermore,the formula for the capacitance $C'$ does not depend on the position of the metallic sheet,provided it is placed parallel to the plates.Therefore,both statements $(a)$ and $(b)$ are correct.

$A$ metallic sheet is inserted between the plates of a parallel plate capacitor. The capacitance of the capacitor
