Before the sheath was there, E was away from wires surface.
Hence electron would be attracted to the wire?
Hence electron would be attracted to the wire?
t_n_p said:I don't get what you mean by offset the charge on the inner wire. I just want to figure out the charge on the inner surface of the sheath..
Are they the same thing?
t_n_p said:I am really, really confused now!
Q/x of sheath = -Q/x for wire = -1.112*10^-12 C/m
Then I use Gauss?
But I want to find Q?
t_n_p said:the exact question..
"A hollow cylindrical metal sheath with inner radius 2mm is now placed around the wire, to form a coaxial cable. What will be the charge on the inner surface of this sheath?"
I'm not sure if they are after a qualitative or quantitative answer, how do you interpret the question?
