3) Using Gauss' Law, prove that the electric field inside a conductor is zero. (Hint: no...
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 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.
Gauss' Law Electric Field Inside a Cavity A sphere of radius 2m is made of a non-conducting material that has a uniform volume charge density p = 2.655 x 10-10C/m. A spherical cavity of radius 1m is then carved out from the sphere. As measured from the center of the large sphere, the center of the spherical cavity is at the position in cos300i+sin 30°i. Find the electric field at a point P within the cavity. As measured from the...
For Gauss' law where is the Electric field evaluated? O All points in space The center of the charge distribution At an arbitrary point in space On the Gaussian surface o It depends on the symmetry An arbitrarily shaped uncharged conductor is added to a field map.
