The symbol . k. is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 10^9 N • m^2 / C^2. . Gabriela Gonz. á. lez. Physics 2102 . Electric Potential on Perpendicular Bisector of Dipole. You bring a charge of -3C from infinity to a point P on the perpendicular bisector of a dipole as shown.. PHENIX Run-15 Run Coordinator. University of New Mexico. Recovery from Power Incidence.
