R = 2F cos 60 = F , α = (θ/2) makes equal angle with both vectors .

Q. Two forces whose magnitudes are in the ratio 3:5 give a resultant of 35N. If the angle between them is $6 0^{\circ}$ , the magnitude of each force is.

3N, 5N

9N, 25N

15N, 25N

21N ,35N

$R = 2 F cos 60 = F, α = \frac{θ}{2}$ makes equal angle with both vectors .
