Question

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 1

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

`|\mu|=|q1q2r|`

so:

`\begin{gathered} |\mu|=|4.4*10^(-9)\cdot-4.4*10^(-9)\cdot0.003| \\ |\mu|=5.808*10^(-20)Cm \end{gathered}`
