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 conductor.
4. [ ] Electric field just outside a charged conductor is perpendicular to the surface and has a magnitude σ/2ε_0.
Homework Answers
(1) False : it states that the net electric flux ΦE through any closed Gaussian surface is equal to the net charge inside the surface divided by ε_0.
(2) True
(3) True
(4) False: Though it will be perpendicular but its value is σ/ε_0, Provided conductor is of infinite size

GAUSS LAW PLEASE ? NEED HELP
Which of the following statements about Gauss's law are correct? (There may be more than one correct choice.)Choose all that apply.The electric flux passing through a Gaussian surface depends only on the amount of charge inside that surface, not on its size or shape.Gauss's law is valid only for symmetric charge distributions, such as spheres and cylinders.If there is no charge inside of a Gaussian surface, the electric field must be zero at points of that surface.Only charge enclosed within...

(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...

Applying Gauss's Law. Spherical Symmetrv: A shell of uniform charge attracts or repels a charged particle that is outside the shell as if all the shell's charge were concentrated at the center of the shell If a charged particle is located inside a shell of uniform charge, there is no electrostatic force on the particle from the shell. Enclosed charge is q Gaussian surface Si The dots represent a spherically symmetric distribution...

Four equal charges are located at the corners of a square of side d. If the magnitude of each charge is doubled, then what happens to the resultant force on each charge? It is doubled. It is quadrupled. It increases by a factor of 8. It remains the same. None Of the other choices is correct. A particle travelling along the +x-axis enters an electric field directed vertically upward along the +y-axis. If the particle experiences a force downward because...
