A long, nonconducting, solid cylinder of radius 3.8 cm has a nonuniform volume charge density rho that is a function of radial distance r from the cylinder axis: rho = Ar2. For A = 2.0 µC/m5, what is the magnitude of the electric field at (a) r = 1.3 cm and (b) r = 5.5 cm.

Two rigid transformations are used to map δhjk to δlmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k
