An infinite line charge produce a field of `7.182xx10^(8)NC^(-1)` at a distance of 2 cm. The linear charge density is

`7.98xx10^(-4)C//m`

`9.11x10^(-4)C//m`

`5.04xx10^(-4)C//m`

`6.27xx10^(-4)C//m`

Text Solution

Verified by Experts

The correct Answer is:

`E=(lamda)/(2piepsi_(0)K)`
`therefore lamda=2pirepsi_(0)KE=(4piepsi_(0)KE r)/(2)=2pi`
