$$k\frac{2{{\lambda }_{1}}{{\lambda }_{2}}}{{{R}^{{}}}}$$

TuteeHUB · Answer

$$k\frac{{{\lambda }_{1}}{{\lambda }_{2}}}{R}$$

1.	Two infinitely long parallel wires having linear charge densities \[{{\lambda }_{1}}\] and \[{{\lambda }_{2}}\] respectively are placed at a distance of \[R\] metres. The force per unit length on either wire will be \[\left( k=\frac{1}{4\pi {{\varepsilon }_{0}}} \right)\]
A.	\[k\frac{2{{\lambda }_{1}}{{\lambda }_{2}}}{{{R}^{2}}}\]
B.	\[k\frac{2{{\lambda }_{1}}{{\lambda }_{2}}}{{{R}^{{}}}}\]
C.	\[k\frac{{{\lambda }_{1}}{{\lambda }_{2}}}{{{R}^{2}}}\]
D.	\[k\frac{{{\lambda }_{1}}{{\lambda }_{2}}}{R}\]
Answer» C. \[k\frac{{{\lambda }_{1}}{{\lambda }_{2}}}{{{R}^{2}}}\]
