A very long conducting tube (hollow cylinder) has inner radiusa and outer radius b. It carries charge per unitlength ?? where ? is a positive constant withunits of C/m. A line of charge lies along the axis of the tube. Theline of charge has charge per unit length +?.
Part B
Find the direction of the electric field in terms of?and the distance r from the axis of the tubeforr<a.
Find the direction of the electric field in termsof  and the distance  from the axis of the tubefor .
| parallel to tube's axis |
| radially outward |
| radially inward |
| the field is zero |
Part D
Find the direction of the electric field in terms of?and the distance r from the axis of the tube fora<r<b.
Find the direction of the electric field in termsof  and the distance  from the axis of the tubefor .
| parallel to tube's axis |
| radially outward |
| radially inward |
| the field is zero |
Part G
What is the charge per unit length on the inner surface of thetube?
Express your answer in terms of the given quantities andappropriate constants.
Part H
What is the charge per unit length on the outer surface of thetube?
Express your answer in terms of the given quantities andappropriate constants.
PLEASE SHOW ALL WORK! Thanks!
