1. The problem statement, all variables and given/known data two point charges in free space are separated by distance d and exert a force 2.6 nN on each other. The force becomes 1.5 nN when the free space is replaced by a homogeneous dielectric material. Calculate the dielectric constant of the material. 2. Relevant equations I used an equation but i did not write it down so I am not totally sure what I used 3. The attempt at a solution 2.6=(9E9)Q^2/d^2 then Q=.000016997d then 1.5=(.000016997d)^2(9e9)/(epsilonr) then epsilonr=1.73 now I have a couple of problems with what I did first I believe I have only found for the relative dielectric constant rather than the dielectric constant. An the second problem is that I did not convert nano newtons to Columbs/m^2N^2 as I wasnt sure of the conversion I searched on google and couldnt find it?
