Question

An infinite line charge produces a field of 9×10^4 N at a distance 2cm . calculate linear charge density .​

Answer 1

Answer:

E = λ/(2πϵor) = 2λ/(4πϵor)

E = 9 x 104 N/C

1/(4πϵo) = 9 x 109  Nm2 /C2.

Linear charge density λ = E. 4πϵor/2

                                         = (9 x 104 N/C) (2 x 10-2 ) / ( (9 x 109  Nm2 /C2) x 2 )

                                        = 10-7 C/m
