Suppose we have a charge, q1=1 μC. This charge makes an electric field some distance r=73 cm away from it. Now suppose our measurement of q1 is only accurate to within 0.2 μC, and our measurement of r is only accurate to within 1.5 cm.

2.3. Two charges are the only charges in a particular region. Arranging a coordinate system so that = one (q1 0.10 C) is at the origin, the other (92 = 0.30 C) is located at the point (6.0 cm, 0). Find the magnitude and direction of the electric field at the following points: a) (3.0 cm, 0) b) (0, 3.0 cm) Be careful in part (b). It takes quite a bit of work, but once you see how to do it, you should see that the same routine can be used to calculate the field at every point in the coordinate system.
