A plane conductor with very large dimensions is charged such that surface charge density is `1.6xx10^(-2)C//m^(2)`. The electric field intensity at a point near it if the conductor is in a medium of dielectric constant 5 is

A

`1.8xx10^(8)V//m`

B

`1.8xx10^(-2)V//m`

C

`1.8xx10^(-6)V//m`

D

`1.8xx10^(2)V//m`

Text Solution

Verified by Experts

The correct Answer is:
A
`E=sigma/(2epsi_(0)k)=(1.6xx10^(-2))/(2xx8.85xx10^(-12)xx5)=1.8xx10^(8)V//m.`
