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. $\mathbf{0}^{\mathbf{0}}\mathbf{,18}\mathbf{0}^{\mathbf{0}}$and$\mathbf{9}\mathbf{0}^{\mathbf{0}}$
• B. $\mathbf{0}^{\mathbf{0}}\mathbf{,9}\mathbf{0}^{\mathbf{0}}$ and $\mathbf{18}\mathbf{0}^{\mathbf{0}}$
• C. $\mathbf{0}^{\mathbf{0}}\mathbf{,9}\mathbf{0}^{\mathbf{0}}$and$\mathbf{9}\mathbf{0}^{\mathbf{0}}$
• D. $\mathbf{18}\mathbf{0}^{\mathbf{0}}$,$\mathbf{0}^{\mathbf{0}}$ and $\mathbf{9}\mathbf{0}^{\mathbf{0}}$

Answer 1

Answer: (A)

$\mathbf{0}^{\mathbf{0}}\mathbf{,18}\mathbf{0}^{\mathbf{0}}$and$\mathbf{9}\mathbf{0}^{\mathbf{0}}$

Answer 2

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 180⁰

For 13N both the vectors should be perpendicular to each other i.e. angle be0tween them should be $90^{0}$
