You are responsible for the material described in assignments sheets 1-4 (including this assignment sheet). You may bring one handwritten sheet of notes and formulae; you should also bring a calculator. You will have the entire class session (80 minutes) to complete the examination. Lecture Topics and Text Readings: 1. Review of the potential energy concept. Application of potential energy to forces from the electric fields of capacitors and point charges (29-1, 2). 2. The concept of an electric potential (29-4), also known as “voltage”. 3. Electric potentials of parallel plate capacitors, point charges, etc. (29-5, 6, 7); contour maps of the electric potential. We will skip section 29-3 on the potential energy of an electric dipole. Mastering Physics
