P218 Review: Conservative forces One-dimensional problem:

Two-dimensional problem: does NOT depend on path! around the closed path is zero!

Chapter 3. Electric Potential Constant electric field The Electric Potential: V - Single Charge - Dipole - conservative? potential energy function?

For a point charge at the origin:

Have a great day! Hw: All Chapter 3 problems and exercises Reading: Chapter 3
