Problem

At a point in space, a

+2.0\,\mu\text{C}

test charge experiences a force of

4.0\times10^{-4}\,\text{N}

directed east. What is the magnitude of the electric field at this point? a)

2.0\times10^{-1}\,\text{N/C}

2.0\times10^{5}\,\text{N/C}

2.0\times10^{2}\,\text{N/C}

4.0\times10^{2}\,\text{N/C}
