If the distance between the plates of two capacitor is increased then capacitance

If the distance between the plates of two capacitor is increased then capacitance

Options

(a) increase
(b) decrease
(c) remains constant
(d) first increase then decrease

Correct Answer:

decrease

Explanation:

Capacitance of a parallel plate capacitor is C = ε₀A / d
where A is the area of a plate and d is the distance between the plates.
or, C ∝ 1 / d
In other words when d increase C decreases.
