Asolid cylinder (centered along the z-axis, bottom face at z =0, top face at z=l, radius r) carries a volume charge distribution p(z) = kz, where k is a positive constant. a. calculate the electric field at an arbitrary point on the z-axis (x= 0, y = 0, z). b. write an integral expression for the electric field at an arbitrary point (x, y, z). c. sketch the electric field.

This chart shows characteristics of three different types of waves. which statement is best supported by the information in the chart? wave x and wave y are mechanical waves, and wave z is an electromagnetic wave. wave x and wave y are electromagnetic waves, and wave z is a mechanical wave. wave x and wave z are electromagnetic waves, and wave y is a mechanical wave. wave x and wave z are mechanical waves, and wave y is an electromagnetic wave.
