1. The Electric field will always be zero inside a conductor that is in electrostatic equilibrium. What if the electric field wasn’t zero?

2. Sometimes an electric ground is called a charge reservoir. Explain why this is appropriate.

3. An electric dipole is a common arrangement of charge in matter; water is one example. Where does the electric field created by an electric dipole become zero? Explain.

4. Sketch the approximate electric field pattern below due to two isolated negative point charges. Be sure to include directions on your electric field lines.

1. The electric potential inside a conductor in equilibrium is (constant or zero?) 2. How would you check whether an electrode is perfectly conductive?

Explain why a conductor in electrostatic equilibrium should have no electric field parallel to its surface,...

Explain why a conductor in electrostatic equilibrium should have no electric field parallel to its surface, nor within its bulk. (Hint: think about forces on a few charged particle).

In electrostatic systems, a potential difference (i.e, a voltage) always corresponds to an electric field. Is this also true about circuits? Specifically, does the potential difference between the two terminals of the battery correspond to an electric field anywhere? Or do circuits allow us to have "voltages without fields?"

An electrical conductor has a net charge h. Explain that the electric field inside conductors equals zero in the electrostatic case and show that the charge is distributed on the conductor surface.

Draw a diagram representing a spherical conductor in static equilibrium with an originally uniform electric field. How does charge density depend on the curvature of an object? Explain one practical application. Calculate the electric field at one corner of a square 20 m on a side if the other three corners are occupied by 2.5 x 10-6 C charges.

1.What would happed to the charges on the surface of a conductor if the electric field was not perpendicular to the surface? 2.Why are electric field lines always perpendicular to equipotential lines? 3.Is it possible for 2 different equipotential lines to pass through the same conductor?

4) Which of the statements about an arbitrarily shaped conductor in electrostatic equilibrium is true? Choose d if more than one is true. a) the electric field strength at some point just outside the conductor is s/e0 where s is the local surface charge density at that point b) the electric field E at the surface is directed tangent (parallel) to the conductor’s surface c) the electric field E is continuous as you move from the inside of the conductor...

A. If the electric field E is zero at a given point, must the electric potential V also equal zero at that point? Explain your reasoning and give an example to prove your answer. B. A positive charge moves in the direction of a uniform electric field. Does its potential energy increase or decrease? Does the electric potential increase or decrease? Explain your reasoning. C. If the electric potential at some point is zero, does it follow that there are...
