Unformatted text preview: Electric Fields Definition: Electric Field E q q Force Field Picture: The source charge q produces an electric field in space. The field pushes on the test charge q . ? Definition: Electric Field = F E q = A vector Exists before test charge is introduced Is produced by other charges (not q ) q is small so as to not disturb the charges producing the field it is a mathematical construct Units : N/C Force on tiny test charge q charge q Example: Calculate the force on an alpha particle (q = +2e) if it is placed in the field. q [ ] = C N E 1000 Repeat for an electron. E Fields are E Fields are Produced by Produced by positive charges, positive charges, and terminate on negative charges and terminate on negative charges Which way will a + or charge move in this field? E Fields between two charged plates E Fields between two charged plates + + + + + + + +-------- Which way will a + or charge move in this field? E Fields are...
