Problem

Two identical point charges of

+2.0\,\mu\text{C}

are fixed at

(−0.20\,\text{m},0)

and

(+0.20\,\text{m},0)

. What is the magnitude of the net electric field at the point

(0,0.30\,\text{m})

? a)

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

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

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

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