Question

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

• A. $0^{\circ },180^{\circ }$ and $90^{\circ }$
• B. $0^{\circ },90^{\circ }$ and $180^{\circ }$
• C. $0^{\circ },90^{\circ }$ and $90^{\circ }$
• D. $180^{\circ },0^{\circ }$ and $90^{\circ }$

Answer 1

Answer: (A)

For $17N$ both the vector should be parallel i.e. angle between them should be zero.
For $7N$ both the vectors should be antiparallel i.e. angle between them should be $180^{\circ }$.
For $13N$ both the vectors should be perpendicular to each other i.e. angle between them should be $90^{\circ }$.
