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

$0^o, 180^o$ and $90^o$

B

$0^o, 90^o$ and $180^o$

C

$0^o, 90^o $ and $90^o$

D

$180^o, 0^o$ and $90^o$

Solution

(a) 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 $180^o$

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