The shell is shown to be nonconducting and equal in charge density.

Okay, so I think I would calculate a) as if it was a radius enclosed in the small cylinder. I'm assume the E is perpendicular to the curved surface. I'm not sure how to determine if the field is perpendicular to the curved surface or the flat circles. b) I would calculate it as a radius...

Also, how do I know if the electric field is directed towards the circular surface of the cylinders or to the curved part?

Homework Statement A very long solid nonconducting cylinger of radius R1 is uniformly charged with a charge density of volume charge densty pE. It is surrounded by a concentric cylinder tube of inner radius R2 and outer radius R3. Determine the electric field as a function of the distance R...
