Question

There are two force vectors, one of $5N$ and other of $12N$. At what angle should the two vectors be added to get the resultant vector of $17N,7N$, and $13N$ respectively?

Answer 1

For $17N$, both the vectors, should be parallel, i.e., angle between thyem should be zero.

For $7N$, both the vectors should be antiparallel, i.e., angle between them should be ${180}^o$

For $13N$, both the vectors should be perpendicular to each other, i.e., angle between them should be ${90}^o$
