Hollow non-conducting cylinder and infinite line charge consider a non-conducting cylinder of infinite length with a hollow core. the inner radius is a, the outer radius is b, and the solid region in between carries a uniformly-distributed volume charge density. a = 3 cm b = 5 cmvolume charge density = +4 microc/m3d = 2 cmcharge per unit length= –0.1 microc/ma)what is the electric field at the position (x, y) =(–b,0) be sure to give both magnitude and direction. b) suppose we add an infinite line charge inside the hollow cylinder, but at an off-center location: the line runs along the line x = d where d < a. the line carries a charge per unit length .
