Problem

Two parallel metal plates are

4.0\,\text{cm}

apart. What potential difference must be applied across the plates to produce a uniform electric field of magnitude

7.5\times10^{3}\,\text{V}\!\bigm/\!\text{m}

between them? a)

1.9\times10^{5}\,\text{V}

3.0\times10^{2}\,\text{V}

1.3\times10^{2}\,\text{V}

3.0\times10^{3}\,\text{V}
