Resultant of East and North Forces
Easyvectorsresultants
Concurrent forces of 3 kN east and 4 kN north act at a point. What is the resultant magnitude?
- A3 kN
- B4 kN
- C5 kN
- D7 kN
Show solutionHide solution
Answer: C. 5 kN
The forces are perpendicular, so R = √(3² + 4²) = √25 = 5 kN. Adding magnitudes directly applies only to forces acting in the same direction.
