True or false: couldnt figure out these few
- When charges are only located OUTSIDE an enclosed Gaussian surface, the number of E field lines entering the surface may be more or less than that of the lines leaving the surface.
- Gauss’s law is not true when there are multiple charges.
- There is zero flux through a closed surface when there are no charge inside or when there are charges inside but the net charge is zero (Same amount of positive and negative charges).

True or false physics 2 questions. 1. [ ] Gauss's law states that the net electric flux ΦE through any closed Gaussian surface is equal to the net charge inside the surface divided by 4πε_0. 2. [ ] Gauss's law is useful for calculating electric field when the charge distribution is highly symmetrical. 3. [ ] At electrostatic equilibrium, the electric field is zero everywhere inside a conductor, and any charge can only be distributed on the surface of the...

(a) We have said that Gauss’s law is always true, but only useful for calculating the electric field created by source charge distributions that are spheres, infinite straight cylinders, and infinite flat sheets, and even those cases have additional restrictions. Explain why we are limited to those distributions. Discuss what additional restrictions apply. For example, can we use Gauss’s law to find the field of a sphere whose density depends on distance r from the center? Can we do it...

surface of radius 12.5 cm. One charge (+3Q =11.4 μC) is inside the
sphere, and the others (charge +Q =3.8 μC) are a distance
4.16666666666667 cm outside the surface.

Use the result to compute the electric field produced by the cylinder at points outside the cylinder (rRcyl). Note that since > Rcyl, the Gaussian surface (with radius r) encloses all the charge in the cylinder. State the direction of the electric field inside and outside the cylinder when a > 0, that is, when the cylinder carries positive charge. Problem...
