Physics

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 termsofÂ Â and the distanceÂ Â from the axis of the tubefor .
parallel to tube's axis
radially outward
radially inward
the field is zero
Part D
