Answer:
It is inversely proportional, so the capacitance increases as the distance decreases.
Step-by-step explanation:
The capacitance of a parallel-plate capacitor is given by:

where
is the vacuum permittivity
A is the area of the plate of the capacitor
d is the distance between the plates
In the formula, we see that the distance (d) is at the denominator: this means that as the distance decreases, the capacitance (C) increases. Therefore, it is an inverse proportionality.
