Point charges q1=− 4.40 nC and q2=+ 4.40 nC are separated by distance 3.00 mm , forming an electric dipole.Find the magnitude of the electric dipole moment.

Answer :

By definition the dipole moment, μ, is the product of the magnitude of the separated charge and the distance of the separation:

[tex]|\mu|=|q1q2r|[/tex]

so:

[tex]\begin{gathered} |\mu|=|4.4\times10^{-9}\cdot-4.4\times10^{-9}\cdot0.003| \\ |\mu|=5.808\times10^{-20}Cm \end{gathered}[/tex]
