Dielectric Constant Of Water

Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.

Electrostatic Potential and Capacitance

An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particle…

Consider a small positive test charge located on an electricfield line at some point, such as point P in Fig. 16–32a. Isthe direction of the velocity and/or acceleration of thetest charge along this line? Discuss.

Assume that the two opposite charges in Fig. 16–32a are12.0 cm apart. Consider the magnitude of the electric field2.5 cm from the positive charge. On which side of thischarge—top, bottom, left, or right—is the electric field thestrongest? The weakest? Explain.

Consider the electric field at the three points indicated by the letters A, B, and C in Fig. 16–49. First draw an arrow at each point indicating the direction of the net force that a positive test charge would experience if placed at that point, then list the letters in order of decreasing field strength (strongest first). Explain. B, FIGURE 16–49 Question 17.
