7. A long thick cylindrical insulating tube of inner radius a and outer radius b carries a uniform volume charge density p, as shown in the diagram. What is the electric field strength at point P a distance d from the surface of the tube? Assume that I >> d. Side view Front view Pb2 2000 P 21€(b+d) p(b2-a?) 2nd P(b2-a?) 2€(b+d)
