PHYS 2002 Lecture : Lecture3
Document Summary
Note: we can also imagine that q2 and q3 create an electric field that q1 interacts with. 18. 6 the electric field: let"s say we have a positive point charge q sitting somewhere in space: Now add nearby positive point charge q0 a distance r from the charge q. F: wherever q0 goes, it feels a force away from q. The charge q0 lives in a force field due to q! If we brought in a larger charge, it would feel a similar force: the electric field of q is called e. 18. 6 the electric field: like the force, the electric field is a vector, the direction of the electric field of q is away from q. Any positive charge near q will be pushed away! Note: any negative charge near q will be attracted: electric field exists everywhere in space and represents the force a charge would feel.
