I plan to use Gauss' Law to calculate the electric field measured at some distance r away from an infinitely long line of charge. Which "Gaussian surface" will exploit the symmetry of this distribution, greatly simplifying my efforts?
A sphere of radius r.
A cylinder of radius r.
A rectangular prism with cross-sectional area of r-squared, alligned along the axis of charge.
All of these surfaces will be equally challenging.
A small spherical surface.
A large spherical surface.
A very small cube.
All surfaces will experience the same net flux.
An isolated positive point charge q is enclosed inside a number of different "Gaussian surfaces." Which of the following surfaces will experience the greatest net flux?Explanation / Answer
1) All surfaces will experience the same net flux.
Reason: flux depends only on amount of charge enclosed and not the geometry.
2) A cylinder of radius r.
On cylindrical surface, teh long line of charge will act as common axis.
