Question

Electric charge is uniformly distributed over a long
straight wire of radius 1 mm.
The charge per cm length of the
wire is a coulombs. A cylindrical
surface of radius 50 cm and length
1m encloses the wire symmetrically
50cm
as shown in fig.
The total flux passing through the cylindrical surface
is :-
