Q. If the distance between parallel plates of a capacitor is halved and dielectric constant is doubled then the capacitance
A) Decreases two times
B) Increases two times
C) Increases four times
D) Remains the same
Explanation
(c) Capacitance with dielectric $C_{medium} = \frac{K\varepsilon_{0}A}{d}$
$\Rightarrow C_{medium} \propto \frac{K}{d}$
