Questions 1.Considering the graphical and analytical methods for obtaining the resultant, whichmethod is more accurate? Give the probable sources of error for each method.
2.Vector subtraction (A-B) is a special case of vector addition, since A-B=A+(-B). Suppose that cases of vector addition I, II, and III in this experiment were vector subtraction (F1-F2). (b) Would the magnitude of the resultant be different for vector subtraction than for vector addition in each case? If so, state whether the subtractive resultant would be greater or less than the additive resultant.
