Considering Figure 18.46, suppose that qa= qdand qb= qc. First show that q is in static equilibrium. (You may neglect the gravitational force.) Then discuss whether the equilibrium is stable or unstable, noting that this may depend on the signs of the charges and the direction of displacement of q from the center of the square.
Using the symmetry of the arrangement, determine the direction of the force on q in the figure below, given that qa=qb=+7.50C and qc = qd = 7.50C. (b) Calculate the magnitude of the force on the charge q, given that the square is 10.0 cm on a side and q = 2.00 C.

An electric field of magnitude 5.25 105 N/C points due south at a certain location. Find the magnitude and direction of the force on a 6.00 C charge at this location.
Calculate the magnitude of the electric field 2.00 m from a point charge of 5.00 mC (such as found on the terminal of a Van de Graaff).
Are the direction and magnitude of the Coulomb force unique at a given point in space? What about the electric field?
If two equal charges each of 1 C each are separated in air by a distance of 1 km, what is the magnitude of the force acting between them? You will see that even at a distance as large as 1 km, the repulsive force is substantial because 1 C is a very significant amount of charge.
Figure 18.44 shows an electric field extending over three regions, labeled I, II, and III. Answer the fallowing questions, (a) Are there any isolated charges? If so, in what region and what are their signs? (b) Where is the field strongest? (c) Where is it weakest? (d) Where is the field the most uniform?
What can you say about two charges q1and q2 if the electric field one-fourth of the way from q1to q2 is zero?
Suppose a woman carries an excess charge. To maintain her charged status can she he standing on just any pair of shoes? How would you discharge her? What are the consequences if she simply walks away?
At what distance is the electrostatic force between two protons equal to the weight of one proton?
Two small silver spheres, each with a mass of 10.0 g, are separated by 1.00 m. Calculate the fraction of the electrons in one sphere that must be transferred to the other to produce an attractive force of 1.00 104 N (about 1 ton) between the spheres. The number of electrons per atom of silver is 47.
