Physics · JEE | Electric Charges and Fields

हिन्दी

Two infinite parallel plane sheets have uniform surface charge densities \( +\sigma \) and \( -\sigma \) respectively. The electric field in the region between the sheets is:

  1. A
    Zero
  2. B
    \( \frac{\sigma}{\varepsilon_0} \)
  3. C
    \( \frac{\sigma}{2\varepsilon_0} \)
  4. D
    \( \frac{2\sigma}{\varepsilon_0} \)
View Answer & Solution

Correct answer · Option B

\( \frac{\sigma}{\varepsilon_0} \)

Explanation

Fields due to both sheets between them point in the same direction, so \( E = \frac{\sigma}{2\varepsilon_0} + \frac{\sigma}{2\varepsilon_0} = \frac{\sigma}{\varepsilon_0} \).
