I'm a little stuck on the theory behind this question:
(in relation to a line of infinite charge: a wire)
A hollow cylindrical metal tube with inner radius 2.5mm is now placed around the wire, to form a coaxil cable. What will be the charge per unit length on the inner surface of the tube. Explain.
I am thinking it is 0, how or why i got that I don't know!
