NCERT · Class 12 · Physics · Electric Charges and FieldsThe magnitude of electric field intensity near an infinite thin plane sheet of uniform surface charge density $\sigma$ is:
Step-by-Step Solution
Using Gauss's Law, the electric field near a thin infinite plane sheet of charge is $E = \frac{\sigma}{2\epsilon_0}$. It is independent of distance $r$ from the sheet.
