Three concurrent co-planar forces 1 N, 2 N and 3 N acting along different directions on a body

  • can keep the body in equilibrium if 2 N and 3 N act at right angle

  • can keep the body in equilibrium if 1 N and 2 N act at right angle

  • cannot keep the body in equilibrium

  • can keep the body in equilibrium in 1 N and 3 N act at an acute angle

Answer

C.

cannot keep the body in equilibrium

If we keep 1 N and 2 N forces act in the same direction then these are balanced by 3 N force, but this is against statement of question.

Hence, options (c) is correct.
