Q2. The force vector A has a magnitude of 87.0 Newton's (N) and points due east. The force vector B has a magnitude of 124 N and points 73.1 ° north of east. Find (a) magnitude and (b) direction of A - B. (Give the direction as a positive angle with respect to due east). Find out the (c) magnitude and (d) direction of B - A. (Give the direction as a positive angle with respect to due west).
