Addition of 2 Perpendicular Vectors
Two forces, P and Q of magnitude 10N and 12N are perpendicular to each other. What is the magnitude of the resultant force if P and Q are acting on an object?
Magnitude of the resultant force
The diagram above shows that four forces of magnitude 2N, 4N, 5N and 8N are acting on point O. All the forces are perpendicular to each other. What is the magnitude of the resultant force that acts on point O?
The resultant force of the horizontal component = 5 – 2 = 3N to the right
The resultant force of the vertical component = 8 – 4 = 4N acting downward.
Therefore, the magtitude of these 2 force components,
