Question

Three forces acting on a particle are in equilibrium. The angle between the first and second is 90degree and that between the second and third is 120degree . Find the ratio of the force​

Answer 1

Answer:

210 degree is te totle an

Answer 2

Explanation:

So the angle between the first and the third forces will be,

By Lami's Theorem, or the law of sines,

Lami's theorem states that if three constant forces make a point in equilibrium, then the ratio of any one force among them to the sine of the angle between the other two forces is the same and is constant.
