Electric field just outside a charged conductor is perpendicular to the surface and has a magnitude σ/2ε.
a. True
b. False

Respuesta :

Answer:

The answer is False

Explanation:

For a infinite sheet of charges, the electric field is perpendicular to its surface. To calculate the electric field, we use a Gaussian surface (cylinder), getting that

[tex]\Phi=E2A=\frac{\sigma A}{\epsilon_{0}}[/tex]

from where

[tex]E=\frac{\sigma}{2\epsilon_{0}}[/tex]

Then the field calculated is one half of the field of a conductor charged with [tex]\sigma[/tex], this means that the magnitude of the charged conductor is

[tex]E=\frac{\sigma}{\epsilon_{0}}[/tex]

Therefore the answer is False.
