  1. Announcements Homework 3 Due Monday Feb. 6 From Ch. 25: problems 3, 14, 16,33,40,44,48 Midterm 1: Monday Feb. 6 Covers chapters 23,24,25 Formula Sheet NOT allowed.

  2. Review Ch. 23, 24, 25

  3. Forces • Force between 2 point charges Coulomb’s Law, superposition • Force on a charge q in an EF: • Fx = q Ex ; Fy = q Ey ; Fy = q Ey

  4. Calculation of an EF • due to a single • point charge Q: Ex=E1x+E2x+E3x+….. Ey=E1y+E2y+E3y+….. • due to many point charges: • due to a continuous • distribution: • Using Gauss Law: When there is symmetry • From the Potential V:

  5. Energy • Potential Energy of a configuration: • Energy of 1 isolated charge: U=0 • Energy of 2 charges: • Energy of many charges: • Energy of a charge q in a potential V: U=qV • CONSERVATION OF ENERGY: Ui+KEi=Uf+KEf

  6. Electric Potential • due to a single point charge: • due to many point charges: • due to a continuous distribution: • from the EF:

  7. Properties of Conductors in electrostatic equilibrium • The EF is zero inside • The electric potential is constant inside and on the surface • The charge is at the surface • The EF at the surface has a magnitude and it is normal to the surface.
