Q.

According to law of triangle of forces

  • AThree forces acting at a point will be in equilibrium
  • BThree forces acting at a point can be represented by a triangle, each side being proportional to force
  • CIf three forces acting upon a particle are represented in magnitude and direction by the sides of a triangle, taken in order, they will be in equilibrium
  • DIf three forces acting at a point are in equilibrium, each force is proportional to the sine of the angle between the other two
Correct Answer : (C)

If three forces acting upon a particle are represented in magnitude and direction by the sides of a triangle, taken in order, they will be in equilibrium

Hints :

According to law of triangle of forces, If three forces acting upon a particle are represented in magnitude and direction by the sides of a triangle, taken in order, they will be in equilibrium.
