The Total solution for NCERT class 6-12
An infinite line chargeproduces a field of 9 × 104 N/Cat a distance of 2 cm. Calculate the linear charge density.
Electric field produced bythe infinite line charges at a distance d havinglinear charge density λ isgiven by the relation,
Where,
d = 2 cm = 0.02 m
E = 9 × 104 N/C
∈0 = Permittivity offree space
= 9 × 109 N m2 C−2
= 10 μC/m
Therefore, the linearcharge density is 10 μC/m.
