Question

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

The correct option is A

$0^{\circ },{180}^{\circ }$ and ${90}^{\circ }$

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