Question

A thin straight infinitely long wire of linear charge density is enclosed by a cylindrical surface of radius r & length l. Its axis coinciding with the length of the wire .
Obtain the expression of the electric field , indicating the directions at a point on the
surface of cylindrical surface ?

Answer 1

Answer:

Charge enclosed by the cylindrical surface = λl By Gauss Theorem, electric flux = 1/εo × charge enclosed. = 1/εo(λl)l.
