JEE Mains · Physics · STD 12 - 1. Electric charges and fields
Three infinitely long charged thin sheets are placed as shown in figure. The magnitude of electric field at the point \(P\) is \(\frac{x \sigma}{\epsilon_0}\). The value of \(x\) is _______. (all quantities are measured in \(SI\) units).
- A \(1\)
- B \(2\)
- C \(5\)
- D \(6\)
Answer & Solution
Correct Answer
(B) \(2\)
Step-by-step Solution
Detailed explanation
\(\overrightarrow{\mathrm{E}}_{\mathrm{p}}=\left(\frac{\sigma}{2 \varepsilon_0}+\frac{2 \sigma}{2 \varepsilon_0}+\frac{\sigma}{2 \varepsilon_0}\right)(-\hat{\mathrm{i}})\) \(=-\frac{2 \sigma}{\varepsilon_0} \hat{\mathrm{i}}\)
