Vector subtraction (F1  F2) is a special case of vector addition, since F1 F2 = F1 + (F2). Use the data (magnitude and direction) of F1 and F2 obtained in measurement 1 to find out the magnitude and direction of the resultant vector of F1  F2.
The data is:
F1: 200g and 30 degrees. F2 = 200g at 120 degrees.
