Question

Two forces of magnitudes are in the ratio 3:5 give a resultant equal to 35N and if the angle between them is 60 degree find magnitude of each force...?? Pls solve

Answer 1

let vectors be 3x and 5x
hence
$\sqrt{9 {x}^{2} + 25 {x}^{2} + 2 \times 5x \times 3x \times \cos(60) } = 35$
$34 {x}^{2} + 30 {x}^{2} \times \frac{1}{2} = 1225 \\ 49 {x}^{2} = 1225 \\ {x}^{2} = 25 \\ x = 5$
vectors are 15 and 25
