Physics - Electrostatics Question with Solution | TestHub

Two long thin rods having charge density ${\lambda }_0\mathrm{x}$ and $-{\lambda }_0\mathrm{x}$ (where x is the distance from their respective centres ${\mathrm{C}}_1$ and ${\mathrm{C}}_2$ ) are placed close and parallel to each other in such a way that distance between their centres is a. Find out the electric field intensity at a point P distant r from this system. ( $\mathrm{k}=\frac{1}{4\pi {ϵ}_0}$ )
