An infinite line charge produces a field of 9 × 104 N/C at a distance of 2 cm. Calculate the linear charge density.
Electric field produced by the infinite line charges at a distance d having linear charge density λ is given by the relation,
d = 2 cm = 0.02 m
E = 9 × 104 N/C
∈0 = Permittivity of free space
`1/(4piin_0)` = 9 × 109 N m2 C−2
= 10 μC/m
Therefore, the linear charge density is 10 μC/m.
