In electrostatic equilibrium
Electric field inside is zero
and entire conductor is at same potential because there is no charge present inside conductor
For a conductor in electrostatic equilibrium, which of the following properties are true? Choose all that...
A solid spherical conductor is charged positively and in electrostatic equilibrium. Which of the following is true. a. the total charge on the conductor must be zero. b. the electric field inside the conductor must be zero. c. any charges on the conductor must be uniformly distributed throughout the sphere. d. the electric field lines are radialy inward from the surface.
Select True or False for the following statements about conductors in electrostatic equilibrium. Charges prefer to be uniformly distributed throughout the volume of a conductor. The electric field inside the conducting material is always zero. All points of a conductor are at the same potential. Just outside the surface of a conductor, the electric field is always zero.
Which of the following are true? Select all that apply. The net electric field inside a block of aluminum is zero under all circumstances. The electric field from an external charge cannot penetrate to the center of a block of iron. The net electric field at any location inside a block of copper is zero if the copper block is in equilibrium. In equilibrium, there is no net flow of mobile charged particles inside a conductor. If the net electric...
The electric potential inside a charged conductor in electrostatic equilibrium A. Is zero B. Is highest at a sharp corner C. Is lowest at a sharp corner D. Depends on the net charge of the conductor
Which of the following statements about electric field lines are true? (choose all that are true) a) They are only defined for positive charges. b) They are always tangent to electric field vectors. c) They are always perpendicular to charged surfaces. d) They are a simple way to visualize the electric field vectors. e) None of the above. If a negative charge is placed in an electric field, what direction will it be accelerated? a) In the direction of the...
The electric field is zero everywhere inside a charged conductor in electrostatic equilibrium. Can you infer that the potential is everywhere zero (Yes/No)? Explain your answer.
The electric field must be zero inside a conductor in electrostatic equilibrium, but not inside an insulator. It turns out that we can still apply Gauss's law to a Gaussian surface that is entirely within an insulator by replacing the right-hand side of Gauss's law, Qin/ε0, with Qin/ε, where ε is the permittivity of the material. (Technically, ε0 is called the vacuum permittivity.) Suppose that a 75 nC point charge is surrounded by a thin, 32-cm-diameter spherical rubber shell and...

I pts Select all statements that are true about electric potential (voltage). it's a vector it depends on the source and not a subject or test charge it can be positive, negative, or zero D only changes in the electric potential are physically meaningful O it is equal to the electric potential energy a conductor in electrostatic equilibrium has the same voltage throughout the interior and surface D it always increases as you move away from any charged object
(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...
