Consider an electric dipole on the x-axis and centered at theorigin. At a distance h = 18.3 cm along the positive x-axis, themagnitude of electric field due to the electric dipole is given byk(2qd)/h3, where q = 6.39 µC and d = 2.50 cm. Find a distanceperpendicular to the x-axis and measured from the origin at whichthe magnitude of the electric field is the same.
