The positive charge, q = 5.98 nC, is located at the point (x, y, z) = (0.00 cm, 14.0 cm, 0.00 cm), while the negative charge is located at the point (x, y, z) = (0.00 cm, -28.0 cm, 0.00 cm). How much work will be done by an electric field É= (12.3 × 105 N/C) i to bring the dipole to its stable equilibrium position? %3D1.
