Charge of uniform density (30 pC/m2) is distributed over a cylindrical surface (radius = 1.0 cm), and a second coaxial surface (radius = 6.0 cm) carries a uniform charge density of -12 pC/m2. Determine the magnitude of the electric field (in N/C) at a point 2.5 cm from the symmetry axis of the two surfaces. Answer is 1.36
