Physics - Electrostatics Question with Solution | TestHub

AB and CD are uniform line charges of infinite length having charge density ${\lambda }_1$ and ${\lambda }_2$ and lying parallel to the Z -axis and X -axis respectively. The force between them depends on the perpendicular distance between them given by ' r ' as shown in figure. The value of $\mathrm{F}=\frac{{\mathbf{\lambda }}_1{\mathbf{\lambda }}_2}{2{\epsilon }_0{\mathrm{r}}^{\mathrm{n}}}$, then write the value of n in OMR sheet.
