An infinitely long uniform line charge distribution of charge per unit length λ lies parallel to the y-axis in the y-z plane at z = 
(see figure). If the magnitude of the flux of the electric field through the rectangular surface ABCD lying in the x-y plane with its centre at the origin is 
(ε 0 = permittivity of free space), then the value of n is :

Sol. Flux from total cylindrical surface (angle = 2p)
= 
Flux from cylindrical surface AB = flux from the given surface
= 
= 
= n = 6
