SUMMARY
The net electric field intensity at the origin due to two charges, Q1 = 2μC located at (3, 4) and Q2 = -10μC at (6, -8), is calculated to be E = 3236i - 10069j. To achieve a net electric field of zero at the origin, a third charge of magnitude 5μC must be placed along the line of the electric field vector in the opposite direction. The exact coordinates for this placement can be determined by dividing the negative of the electric field vector by the constant k associated with the charge's influence.
