Question

A large conducting sheet is having surface charge density $\sigma$. Electric field at a point close to it is

(${\epsilon }_0$ is permittivity of free space)

$[$0.77 Mark$]$

• A. $\frac{\sigma }{2{\epsilon }_0}$
• B. $\frac{\sigma }{8{\epsilon }_0}$
• C. $\frac{\sigma }{4{\epsilon }_0}$
• D. $\frac{\sigma }{{\epsilon }_0}$

Answer 1

The correct option is A $\frac{\sigma }{2{\epsilon }_0}$

Electric field near a conducting sheet having surface charge density $\sigma$ is $E=\frac{\sigma }{2{\epsilon }_0}$
