Question1
The force vector A has a magnitude of 91.0 Newton’s and points due east. The force vector B has magnitude of 134 Newton’s and points 78° north of east. Utilize the graphical method and find out the magnitude and direction of following forces.
(a) Vector Fa − Vector Fb (give the direction with respect to due east)
(b) Vector Fb − Vector Fa (give the direction with respect to due west).
