Addition Of Vectors

Concept: Diagonal of parallelogram:

Step 1: Add vectors.


Step 2: Find magnitude.

Concept: Collinearity implies vectors are scalar multiples.

Step 1:Given conditions

Step 2:Substitute in first equation

Step 3:Use magnitudes Similarly:

Step 4:Valid case (non-trivial geometry) Taking consistent values gives symmetric configuration leading to: From valid scalar choices: Conclusion : {3}
