Problem

A test charge of

+2\,\mu\text{C}

experiences a constant force of

4\,\text{mN}

in a region of space. Calculate the magnitude of the electric field at that point. (a)

5\times10^{-4}\,\text{N/C}

(b)

4\times10^{3}\,\text{N/C}

(c)

2\times10^{3}\,\text{N/C}

(d)

2\times10^{6}\,\text{N/C}
