NEET · Physics · STD 12 - 1. Electric charges and fields
Two parallel infinite line charges with linear charge densities \(+\lambda\; \mathrm{C} / \mathrm{m}\) and \(-\lambda\; \mathrm{C} / \mathrm{m}\) are placed at a distance of \(2 \mathrm{R}\) in free space. What is the electric field mid-way between the two line charges?
- A Zero
- B \(\frac{2 \lambda}{\pi \epsilon_{0} \mathrm{R}} \mathrm{N} / \mathrm{C}\)
- C \(\frac{\lambda}{\pi \mathrm{e}_{0} \mathrm{R}} \mathrm{N} / \mathrm{C}\)
- D \(\frac{\lambda}{2 \pi \epsilon_{0} R} \mathrm{N} / \mathrm{C}\)
Answer & Solution
Correct Answer
(C) \(\frac{\lambda}{\pi \mathrm{e}_{0} \mathrm{R}} \mathrm{N} / \mathrm{C}\)
Step-by-step Solution
Detailed explanation
\(\overrightarrow{\mathrm{E}}=\overrightarrow{\mathrm{E}}_{1}+\overrightarrow{\mathrm{E}}_{2}\) \(\mathrm{E}=\mathrm{E}_{1}+\mathrm{E}_{2}\)
