The electron beam in a certain cathode ray tube possesses cylindrical symmetry, and the charge density is represented by:
ρv= -0.1 / (ρ2 + 10-8) pC/m3 for 0<ρ<3x10-4m, and ρv= 0 for ρ<3x10-4m.
(a) Find the total charge per meter along the lenght of the beam.
(b) if the electron velocity is 5x10-7 m/s, and 1ampere defiined as 1 C/s, find the beam current.
