The electric intensity due to a charged conducting cylinder of radius 0.1 m at a distance of 1 m from the axis of the cylinder of charge density `1.77muC//m` in a dielectric medium of dielectric constant 2 is

A

`2xx10^(5)V//m`

B

`1.5xx10^(4)V//m`

C

`2.59xx10^(5)V//m`

D

`4xx10^(5)V//m`

Text Solution

Verified by Experts

The correct Answer is:
B
`E=1/(4piin_(0)k)(2q)/r=(9xx10^(9)xx2xx1.77xx10^(-6))/(2xx1)`
`=1.593xx10^(3)V//m`
