d) Assigned questions 1,2 and 31) Considering the graphical and analytical methods for obtaining the resultantwhich method is more accurate? Give the probable source of error for each method.,
2)Vector subtraction (A-B) is a special case of vector addition,since A-B=A+(-B) Suppose that the cases of vector addition 1,2 and 3 in the experiment were vector subtraction (F1-F2).
a) What effect would this have on the directions of the resultants? (Do not calculate explicitly.Simply state in which quadrant the resultant would be in each case.)
b) Would the magnitude of the resultant be different for vector subtraction that for vector addition in each case? If so,state whether the subtractive resultant would be greater or less then the additive resultant.
3 A picture hangs on nail as shown in Fig 7.The tension T in each string segment is 3.5Na) What is the equilibrant or the upward reaction force of the mail?
b) What is the weight of the picture?
