An infinite line charge produces a field...

An infinite line charge produces a field of `9 xx 10^(4)N//C` at a distance of 2cm. Calculate the linear charge density.

Text Solution

Verified by Experts

`E=9 xx 10^(4) NC^(-1), r=2cm =2 xx 10^(-2)m`
`E=9 xx 10^(9) xx (2lambda)/(r)`
`lambda=(Er)/(9 xx 10^(9) xx 2)=(9 xx 10^(4) xx 2 xx 10^(-2))/(9 xx 10^(9) xx 2)=0.1 muC//m`
