Problem

A parallel-plate capacitor is built from two square aluminum plates, each of side length

6.0\,\text{cm}

, separated by

1.5\,\text{mm}

of air. The plates are then connected to a

90\,\text{V}

battery and fully charged. Calculate the magnitude of the charge residing on each plate (in coulombs).
