A conductor having a charge density of `120muC//m^(2)` is surrounded by a medium of dielectric constant 4. The electric intensity at a point very near the charged conductor is

A

`9.33xx10^(6)N//C`

B

`3.39xx10^(8)N//C`

C

`9.33xx10^(8)N//C`

D

`3.389xx10^(6)N//C`

Text Solution

Verified by Experts

The correct Answer is:
D
`E=sigma/(in_(0)k)=(120xx10^(-6))/(8.85xx10^(-12)xx4)`
`=3.389xx10^(6)N//C`
