1. The problem statement, all variables and given/known data Specify the strength of the electric field. Let r = 7.3cm . 2. Relevant equations E1= (k*p)/(r^2+a^2)^3/2 Here k= constant used in Coulomb's law. a= half the length of dipole p= dipole moment = charge x length of dipole. Charge = 3nC and length of dipole 3. The attempt at a solution E1= (9E9)(3E-9)/(.146)^2+(.073)^2)^(3/2)= 6207 I got this wrong, but does anyone have any advice on how to solve this?
