Problem

Two identical square plates are made by cutting an aluminium sheet of density

2700\,\text{kg\,m}^{-3}

and thickness

0.010\,\text{mm}

. Each plate has a mass of

4.32\,\text{g}

. The plates are arranged parallel to each other in air with a separation of

1.0\,\text{mm}

. Calculate the capacitance of this capacitor.
