Unformatted text preview: q 3 = (5/4) q 1 , express the magnitude  F 3  of the total electric force on q 3 in terms of the Coulomb force constant k , the charge q 1 , the distances a and b , and the angle _ between the xaxis and the line joining q 1 and q 3 . Express the direction _ of the total electric force on q 3 in terms of _ . Draw a diagram to illustrate your definition of _ . Part II: Test that your expressions work by considering the following two special cases: i) q 3 is located on the x axis, coordinates (0, 0) ii) q 3 is located very far up the y axis, so that b _ First, find F 3 for each special case. Then, show that your expressions for F 3 from Part I reduce to the correct answers in each of these two special cases....
