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 / Eo, with Qin /ɛ, where ε is the permittivity of the material. (Technically, so is called the vacuum permittivity.) Suppose that a 75 nC point charge is surrounded by a thin, 32-cm-diameter spherical...
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...

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
3.1 Pre-lab In the lab on electric potential and electric field lines, you noted that charged par- ticles produce electric fields and these electric fields, in turn, act on charged par- ticles. However, you then proceeded to produce an electric field geometry using conductors held at a particular electric potential. What happened to the electric charges? Electric charge and electric potential are closely related to each other. Putting charge on a conductor raises its electric potential. It is usually much...
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...
