An infinite line charge produces a field of `9xx10^(4)` N/C at a distance of 2 cm calculate the linear charge density

Text Solution

Verified by Experts

Electric field at perpendicular distance r from an infinitely extended uniform line of charge is,
`E = (2klambda)/r`
`therefore lambda = (Er)/(2k)`
`=(9 xx 10^(4) xx 0.02)/(2 xx 9 xx 10^(9))`
`therefore lambda =10^(-7) C//m`
