due east = 30 N
due west = 50 N
force due x axis = -20 N
due north = 20 N
due south = 40 N
force due y axis = - 20 N
Resultant force = √(-20)² + (-20)²
= √400 + 400
= √800
= √2 x 2 x 2 x 10 x 10
= 20√2 N
due west = 50 N
force due x axis = -20 N
due north = 20 N
due south = 40 N
force due y axis = - 20 N
Resultant force = √(-20)² + (-20)²
= √400 + 400
= √800
= √2 x 2 x 2 x 10 x 10
= 20√2 N
