SUMMARY
The electric field at the origin, located between point charges +q and -q positioned at +50 cm and -50 cm on the x-axis, is nonzero. The electric field vectors from each charge at the origin point in opposite directions; the positive charge contributes a field directed away from itself, while the negative charge contributes a field directed towards itself. The resultant electric field at the origin is directed from the positive charge towards the negative charge, confirming that the field is indeed nonzero.
