A charge of `5xx10^(-10)C` is given to a metal cylinder of length 10 cm, placed in air. The electric intensity due to the cylinder at a distance of 0.2 m from its axis is

A

`150V//m`

B

`250V//m`

C

`350V//m`

D

`450V//m`

Text Solution

Verified by Experts

The correct Answer is:
D
`E=1/(4piin_(0)k)(2q)/(rL)=(9xx10^(9)xx2xx5xx10^(-10))/(1xx0.2xx0.1)`
`=450V//m`
