Problem

An isolated parallel-plate capacitor (vacuum between plates) stores a charge of

50\,\mu\text{C}

at a potential difference of

200\,\text{V}

. If the plate separation is

2\,\text{mm}

, what is the required plate area? a)

5.7\times10^{0}\,\text{m}^{2}

5.7\times10^{-2}\,\text{m}^{2}

5.7\times10^{1}\,\text{m}^{2}

5.7\times10^{2}\,\text{m}^{2}
