Forces P, Q, and S of magnitudes 6.00 N, 10.00 N, and 8.00 N respectively, act on point O such that the angle made by force P is 50° counter clockwise from the positive x-axis, force Q acts at an angle of 38° counter clockwise from the negative y-axis, and force S acts at an angle of 32° counter clockwise from the positive y-axis. The magnitude of the resultant vector R is:
A. 8.36 N
B. 6.76 N
C. 45.7 N
D. 2.28 N
E. 9.28 N
