The electric field strength $1\mathrm{.}5$ cm from an electric dipole, on the axis of the dipole, is $1\mathrm{.}5$ times $10\mathrm{⁵}$ N$/$C$.$ What is the dipole moment in nC $?$ What is the magnitude of each of the dipole's charges if they are $1\mathrm{.}0$ mm apart? If the dipole is replaced by a single charge, what magnitude charge in nC will give the same field strength $1\mathrm{.}5$cm away?
