The figure shows two snapshots of a single wave on a string. The wave is
traveling to the right in the +x direction. The solid line is a snapshot of the wave
at time t=0 s, while the dashed line is a snapshot of the wave at t=0.48s.

An extremely long, solid nonconducting cylinder has a radius Ro. The charge density within the cylinder is a
function of the distance R from the axis, given by PE (R) = po(R/Ro)², po > 0.
