Question

For an infinitely long, straight wire, what does \[\lambda\] represent, and what is its SI unit?

विकल्प

• Volume charge density; C/m³

• Surface charge density; C/m²

• Linear charge density; C/m

• Total charge; C/m

Answer 1

The symbol \[\lambda\] denotes linear charge density for the wire. Its SI unit is coulombs per metre, written C/m.
