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` |
