A parallel plate air condenser has capacity of 20μF. If the distance between two plates is doubled, then new capacity will be ________.

The correct option is C 10μFC=ϵ0Ad, Where, A is overlapping area of the plates, d = distance between the two platesThus, capacity is inversely proportional to the distance between the plates.Thus, if the distance between the plate is doubled, the capacity is halved.

A parallel plate air condenser has capacity of $20 μ F$ . If the distance between two plates is doubled, then new capacity will be ________.

The correct option is C $10 μ F$
$C = \frac{ϵ_{0} A}{d}$ ,
Where, $A$ is overlapping area of the plates, d $=$ distance between the two plates
Thus, capacity is inversely proportional to the distance between the plates.
Thus, if the distance between the plate is doubled, the capacity is halved.
