Problem

A test charge of

q = -1.5\,\mu\text{C}

at the origin experiences a force given by

\vec F = (3.0\,\hat i - 4.0\,\hat j)\times10^{-3}\,\text{N}

. Which vector best represents the electric field

\vec E

at the origin? a)

(2.0\times10^{3}\,\hat i-2.7\times10^{3}\,\hat j)\,\text{N/C}

b)

(-2.7\times10^{3}\,\hat i+2.0\times10^{3}\,\hat j)\,\text{N/C}

c)

(-2.0\times10^{3}\,\hat i+2.7\times10^{3}\,\hat j)\,\text{N/C}

d)

(2.0\times10^{3}\,\hat i+2.7\times10^{3}\,\hat j)\,\text{N/C}
