Question

Electric charge is uniformly distributed along a long straight wire of radius 1mm the charge per cm length of a wire is qcoul

Answer 1

your question is incomplete. A complete question is ----> Electric charge is uniformly distributed along straight wire of radius 1 mm. The charge per cm length of the wire is Q coulomb. Another cylindrical surface of radius 50 cm and length 1 m symmetrically encloses the wire. The total electric flux through the cylindrical surface is.

solution : charge enclosed inside the cylinderical surface is , $Q_{en}$ = linear charge density of wire × length of cylinder

= Q coulomb/cm × 100cm = 100Q Coulombs

now, from Gauss theorem,

electric flux through cylindrical surface = charge enclosed/permittivity of medium

= $\frac{100Q}{\epsilon_0}$
