  1. The electrostatic constant is 9 x 10 9 N m2/C2 It appears on the AP B reference tables this way and it’s the easiest form to use. Annoyingly, it appears as 8.99x 10 9 Nm2/C2 on the Regents Reference Tables Many ways to say “k” However, this constant only works for charges in a vacuum. K changes if the environment is water, glass, plastic etc. ( a “dielectric”) In those materials k can be adjusted using another constant;  k = 1/4 where epsilon is called the electrical permittivity of the dielectric substance.  is minimum for a vacuum 8.85 x 10 –12 C2/N m2. Then it is called the “permittivity of free space” o.However the AP never requires you to ever actual use . So just stick with 9 x 10 9.
