Two negative point charges -Q are held in place. A positive test charge qo is moved in the vicinity of the two point charges. Points A and B are equidistant from the two point charges, and the line through B and C is parallel to the line joining the point charges: A. Which physical property is represented by the dashed lines in the Figure? C B. Is the work done by the electric force (Coulomb force) on the test charge positive, negative, or zero when the test charge is moved from A to B? Explain. C. Is the work done by the electric force on the test charge positive, negative, or zero when the test charge is moved from B to C? Explain D. A charge of +2Q is now put in position D, just between the two original charges. Is the work done by the total electric force on the same original test charge positive, negative, or zero if it again is moved from A to B? Explain.
