According to Law of Triangle of Forces_____.

three forces acting along the sides of a triangle are always in equilibrium

three forces acting at a point, can be rep-resented by the sides of a triangle, each side being in proportion to the force

if three forces acting at a point are in equilibrium each force is proportional to the sine of the angle between the other two

All of the aboif the forces acting on a particle be represented in magnitude and direction by the two sides of a triangle taken in order, their resultant will be represented in magnitude and direction by the third side of the triangle, taken in opposite order.ve

Correct Answer : if the forces acting on a particle be represented in magnitude and direction by the two sides of a triangle taken in order, their resultant will be represented in magnitude and direction by the third side of the triangle, taken in opposite order.
