Gauss Law Work
Gauss’ Law
1. Which of the following graphs best represents the electric field along the positive x‑axis?
2. Above a charge on a wire loop created an electric field. Now imagine a wire loop in an electric field.
a. Draw a diagram to show the relative orientation of the loop and the electric field so that the number of field lines that pass through the surface of the loop is maximum possible.
b. Draw a diagram to show the relative orientation of the loop and the electric field so that the number of field lines that pass through the surface of the loop is minimum possible.
3. What is electric flux?
4. A cube has edge lengths of 1.40 m and is oriented in a region of uniform electric field. Find the electric flux through the right face if the electric field, in Newtons per Coulomb is given by
a. E=(6.00–2.00) N/C
b. E=(–3.00i+4.00k) N/C
c. What is the total flux through the cube for each of these fields?
5. Examples of electric flux
a. A positive charge inside a sphere
b. A negative charge inside a sphere
c. A positive and negative charge inside a sphere
d. A cylinder in a uniform electric field
e. A box next to a positive charge
6. The net electric flux through a closed surface is
a. infinite only if there are no charges enclosed by the surface
b. infinite only if the net charge enclosed by the surface is zero
c. zero if only negative charges are enclosed by the surface
d. zero if only positive charges are enclosed by the surface
e. zero if the net charge enclosed by the surface is zero
7. In the following figure, a Gaussian surface enclosing part of a distribution of four positive charges.
