95 Questions for Chapter 19: Electric Potential and Electric Field

  1. How far apart are two conducting plates that have an electric field strength of \(4.50 \times {10^3}\;V/m\) between them, if their potential difference is \(15.0kV\)?

    Found on Page 696

  2. In what region of space is the potential due to a uniformly charged sphere the same as that of a point charge? In what region does it differ from that of a point charge?

    Found on Page 694

  3. Which methods of radiation protection were used in the device shown in the first photo in Figure 32.35? Which were used in the situation shown in the se

  5. Fusion probability is greatly enhanced when appropriate nuclei are brought close together, but mutual Coulomb repulsion must be overcome. This can be done using the kinetic energy of high-temperature gas ions or by accelerating the nuclei toward one another.

  6. What is an equipotential line? What is an equipotential surface?

  8. Explain in your own words why equipotential lines and surfaces must be perpendicular to electric field lines.

  9. Consider a battery used to supply energy to a cellular phone. Construct a problem in which you determine the energy that must be supplied by the battery, and then calculate the amount of charge it must be able to move in order to supply this energy. Among the things to be considered are the energy needs and battery voltage. You may need to look ahead to interpret manufacturer's battery ratings in ampere-hours as energy in joules.
