A thin-walled hollow circular glass tube, open at
both ends, has a radius R and length L. The
axis of the tube lies along the x axis, with the
left end at the origin. The outer sides are
rubbed with silk and acquire a net positive
charge Q distributed uniformly. Determine the
electric field at a location on the x axis, a
distance w from the origin. Carry out all steps,
including checking your result. Explain each
step. (You may look up the integral).
