Physics Text Notes 1/26/07 Chapter 22 Electric Fields The Electric Field Assumption: each charge sets up an electric field in the space around it. The electrostatic force  acting on any one charge is then due to the electric field set up at its location by another charge The  electric field  is a vector field; it consists of a distribution of vectors, one for each point in  the region around the charged object We can define the electric field at some point near the charged object, point P:  we place a positive charge  q 0 , called a test charge at the point we then measure the electrostatic force that acts on the test charge we define the electric field E at point P due to the charged object as: E = F/ q 0  the magnitude of the electric field at point P is E = F/ q 0 , and the direction of E is that of the  force F that acts on the positive test charge  the SI unit for the electric field is  Newton per coulomb (N/C)
