Question

Two parallel infinite line charges with linear charge densities $+λ \frac Cm$ and $-λ \frac Cm$ are placed at a distance of $2R$ in free space. What is the electric field mid-way between the two line charges

• A. zero
• B. \frac{2\lambda}{\pi\epsilon_0R}$$N/C
• C. \frac{\lambda}{\pi\epsilon_0R}$$N/C
• D. \frac{\lambda}{2\pi\epsilon_0R}$$N/C

Answer 1

Answer: (C)

\frac{\lambda}{\pi\epsilon_0R}$$N/C

Answer 2

The correct option is (C) :\frac{\lambda}{\pi\epsilon_0R}$$N/C
