79. From the second measurement (at (2.0, 0)) we see that the charge must be somewhere on the xaxis. A line passing through (3.0, 3.0) with slope 1tan (3 4)−will intersect the xaxis at x= –1.0. Thus, the location of the particle is specified by the coordinates (in cm): (–1.0, 0). (a) The xcoordinate is
