Two parallel infinite line charges with linear charge densities $+ λ C m^{- 1}$ and $- λ C m^{- 1}$ are placed at a distance of $2 R$ in free space. What is the electric field mid-way between the two-line charges?NEET 2019 (All India)

Options:

Answer:

Solution:

$E_{1} = \frac{λ}{2 π ε_{0} R}$
$E_{2} = \frac{λ}{2 π ε_{0} R}$
$E_{net} = E_{1} + E_{2}$
$= \frac{λ}{π ε_{0} R} N C^{- 1}$
