Two infinitely long thin straight wires having uniform linear charge densities $2 λ &4 λ$ are arranged parallel to each other at a distance R apart. The intensity at a point midway between them is :-

Options:

Answer:

Solution:

$E_{1} = \frac{2 K ( 2 λ )}{( \frac{R}{2} )} \Rightarrow \frac{8 K λ}{R}$

$E_{2} = \frac{2 K ( 4 λ )}{( R /2 )} \Rightarrow \frac{16 K λ}{R} E_{net} = \frac{8 K λ}{R} = \frac{8 λ}{R} \cdot (\frac{1}{4 π ϵ _{0}}) = \frac{2 λ}{π ϵ _{0} R}$
