A charged cylinder of radius 3 mm has surface density of charge `4muC//m^(2)`. It is placed in a medium of dielectric constant 6.28. The electric intensity at a point at a distance of 1.5 M from its axis is

A

`1.44V//m`

B

`2.44V//m`

C

`3V//m`

D

`0.5V//m`

Text Solution

Verified by Experts

The correct Answer is:
A
`E=(sigmaR)/(epsi_(0)kr)=(4xx10^(-6)xx3xx10^(-3))/(8.85xx10^(-12)xx6.28xx1.5)`
`=1.44V//m.`
