Problem

An electric field does

4.5\times10^{-4}\,\text{J}

of work on a

-3.0\,\text{nC}

charge as the charge moves from point X to point Y. What is the electric potential difference

V_{Y}-V_{X}

? a)

-1.5\times10^{5}\,\text{V}

+1.5\times10^{3}\,\text{V}

+1.5\times10^{5}\,\text{V}

+1.5\times10^{4}\,\text{V}
