Point Charges,Q₁ = +46 NC and Q₂ = -75 NC,are

Point charges,Q₁ = +46 nC and Q₂ = -75 nC,are placed as shown.In the figure,an external force transports an electron from point A to point B.The work done by the external force is closest to:

A) + 730 eV
B) + 610 eV
C) + 480 eV
D) - 730 eV
E) - 480 eV
