Electric Field and Equipotential Lines Purpose To gain some experience with equipotential lines and electric fields by experimentally determining the potential at various points between test charges and then drawing in the equipotential lines and the electric field lines. Preliminary Discussion The concept of a field surrounding the source of a force is a very important concept for all of physics. For this experiment , it is intended that you gain some experience with electric fields, study some of their effects, and make some measurements of the strengths of their sources. You have already worked with one example of a vector field, the gravitational field (g). With every point in space near the earth we have associated a gravitational field vector g, which is the gravitational acceleration that a test body placed at that point and released, would experience. If m is the mass of the body and F the gravitational force (“weight”) acting on it, g is given by g = F /m [Newton/kg] ……(1.1) This kind of

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
