A wire with a negligible diameter is coaxial with a very thin cylindrical shell of radius R=4.79cm. Both are composed of an insulating material, and for practical purposes, they are infinitely long. The wire has a uniform linear charge density, λ1=−112pC/m, and the cylinder has a linear charge density, λ2=+531pC/m, that is uniformly distributed around its circumference. a. If r is the distance from the wire, then what is the magnitude, in newtons per coulomb, of the electric field at r=3.08cm. b. If r is the distance from the wire, then what is the magnitude, in newtons per coulomb, of the electric field at r=8.81cm.
