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