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

Options

  1. Acan keep the body in equilibrium if 2 N and 3 N act at right angle
  2. Bcan keep the body in equilibrium if 1 N and 2 N act at right angle
  3. Ccannot keep the body in equilibrium
  4. Dcan keep the body in equilibrium in 1 N and 3 N act at an acute angle

Correct answer

C. cannot keep the body in equilibrium

Step-by-step solution

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