An infinite line chargeproduces a fieldof 9xx10^(4) N/Cat a distance of 2 cm calculate the linear charge density

Answer»

SOLUTION :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`
