Physics

Two long, charged, thin-walled, concentric cylindrical shellshave radii of 3.9 and 9.4 cm. The charge per unit length is 6.8 ×10-6 C/m on the inner shell and -8.5 × 10-6C/m on the outer shell. What are the (a) magnitudeE and (b) direction (radially inward oroutward) of the electric field at radial distance r = 5.9cm? What are (c) E and(d) the direction at r = 14 cm?
