Calculate the resultant force when four forces of 30N due east 20N due north 50N due West and 40N due south are acted upon a body

Answer 1

F=30E+20N+50W+40S
=30E+20N-50E-40N
=-20N-30E

force magnitude=sqrt(20^2+30^2)
direction arctan(20/30) + 180 deg

Answer 2

Find magnitude and direction of resultant force if 50 N force is acting due North and 30 N force is acting due East
