Question

For a uniformly charged thin insulating infinite plane sheet, what does \[\sigma\] represent, and what is its SI unit?

विकल्प

• Linear charge density; C/m

• Surface charge density; C/m²

• Total charge; C

• Volume charge density; C/m³

Answer 1

The sheet's charge is described by its surface charge density \[\sigma\]. The SI unit for surface charge density is C/m².
