Physics - Elecrostatics Question with Solution | TestHub

An electric dipole is placed on$x-$axis in proximity to a line charge of linear charge density$3.0\times {10}^{-6} \mathrm{C} {\mathrm{m}}^{-1}.$Line charge is placed on$\mathrm{z}-$axis and positive and negative charge of dipole is at a distance of$10 \mathrm{mm}$and$12 \mathrm{mm}$from the origin respectively. If total force of$4 \mathrm{N}$is exerted on the dipole, find out the amount of positive or negative charge of the dipole.
