Determining net force on a test charge As vector fields, electric fields exhibit properties typical of vectors and thus can be added to one another at any point of interest. Thus, given charges q 1, q 2,… q n, one can find their resultant force on a test charge at a certain point using vector addition: adding the component vectors in each direction and using the …
