If two force vectors F1 & F2 with the angle between them θ acting on a body simultaneously, then the resultant force is _______
1
\([{F_1^2 + F_2^2 - 2{F_1}{F_2}\cos \theta}]^{1/2}\)
2
\([{F_1^2 + F_2^2 + 2{F_1}{F_2}\cos \theta}]^{1/2}\)
3
\([{F_1^2 + F_2^2 - 2{F_1}{F_2}\sin \theta}]^{1/2}\)
4
\([{F_1^2 + F_2^2 + 2{F_1}{F_2}\sin \theta}]^{1/2}\)
5
\([{F_1^2 + F_2^2 + 2{F_1}{F_2}\tan \theta}]^{1/2}\)
