An infinite plane sheet of charge having uniform surface charge...

An infinite plane sheet of charge having uniform surface charge density +σsC/m2+\sigma_s \mathrm{C} / \mathrm{m}^2 is placed on x−yx-y plane. Another infinitely long line charge having uniform linear charge density +λeC/m+\lambda_e \mathrm{C} / \mathrm{m} is placed at z=4 mz=4 \mathrm{~m} plane and parallel to yy-axis. If the magnitude values \left|\sigma_{\mathrm{s}}\right|=2 \left|\lambda_e{\mathrm{e}}\right| then at point (0,0,2)(0,0,2), the ratio of magnitudes of electric field values due to sheet charge to that of line charge is πn:1\pi \sqrt{n}: 1. The value of nn is_______.An infinite plane sheet of charge having uniform surface charge density +σ_s C / m^2 is placed on x-y plane. Another

Step-by-step solution

An infinite plane sheet of charge having uniform surface charge density +σ_s C / m^2 is placed on x-y plane. Another
ESEℓ=σ2ϵ0×2πϵ0rλ=π×σrλ=π×2λ×2λ=4π1∴n=16\begin{aligned} & \frac{\mathrm{E}_{\mathrm{S}}}{\mathrm{E}_{\ell}}=\frac{\sigma}{2 \epsilon_0} \times \frac{2 \pi \epsilon_0 \mathrm{r}}{\lambda} \\ & =\frac{\pi \times \sigma \mathrm{r}}{\lambda} \\ & =\frac{\pi \times 2 \lambda \times 2}{\lambda}=\frac{4 \pi}{1} \\ & \therefore \mathrm{n}=16\end{aligned}
