A) (−16.5 cm, 0) B) (−14.5 cm, 0) C) (2.49 cm, 0) D) 1(0, 0) E) (−6.50 cm, 0 ... A point charge {eq}q = -0.27\ nC {/eq} is fixed at the origin. Where must an electron be placed in order for the electric force acting on it to be exactly opposite to its weight? It is clear, from Coulomb's law, that the electrostatic force exerted on any charge placed on this line is parallel to the -axis. Thus, the electric field at any point along this line must also be aligned along the -axis. Let the -coordinates of charges and be and , respectively. It follows that the origin lies

If charge q is placed at a point where the electric field is E, it will experience a force (F) such that. F = qE. This is because of the fact that, for example, for a point charge we may write the Coulomb's law as . F = q 2 (kq 1 /r 2) or, F = q 2 E 1. E 1 is the electric field of charge q 1. q 2 is in the field of q 1. In general, F = q E

To find electric potential due to a dipole consider charge -q is placed at point P and charge +q is placed at point Q as shown below in the figure. Since electric potential obeys superposition principle so potential due to electric dipole as a whole would be sum of potential due to both the charges +q and -q.
