Four charged particles lie along the
axes of the x y coordinate plane.
• Positive charge q, is above the
origin.
• Negative charge q, is below the
origin by a distance approximately
equal to the distance q, is above
the origin.
• Positive charge q, is at the origin.
• Positive charge q, is to the right of
the origin.
