Chapter 5.3, Problem 1aT

In the following Questions, a Gaussian cylinder with radius a andl is placed in various electric fields. The end caps are labeled A and C and the side surfaces is labeled B. In each case, base your answer about the net flux only on qualitative arguments about the magnitude of the flux through the end caps and side surfaces.

A. The Gaussian cylinder is in uniform electric field of magnitude $E_o$ aligned with the cylinder axis.

• Find the sign and magnitude of the flus through:

Surface A:  Surface B:  Surface C:

• Is the net flux through the Gaussian surface positive, negative, or zero?
