A very small charge q0 is placed at a point ~r in space. This region contains a number of other charged particles that are at fixed locations. Because these charges are fixed, adding q0 does not change their locations. You measure the force on q0 (F~ on q0 ) and use this to conclude that the electric field at point ~r is E~= F~on q0 q0 . If the charge is replaced by q1 = −q0 4 , and the process above is repeated, then the electric field at point ~r inferred from the force on q1 (F~ on q1 ) would be closest to: (a) E~ 4 (b) -E~ (c) -4E~ (d) E~ (e) None of the above
