Two long concentric cylindrical conductors of radii a and b (b < a) are maintained at a potential difference V and carry equal opposite current I. Show that an electron with a particular velocity u parallel to the axis may travel undeviated in the evacuated region between the conductors.

i need to show me the graph so i can give u an answer

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

report!

explanation:

physics means: "the branch of science concerned with the nature and properties of matter and energy. the subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light and other radiation, sound, electricity, magnetism, and the structure of atoms."
