Three concurrent co-planar forces 1 ~N , 2 ~N and 3 ~N acting along different directions on a body
Options
- Acan keep the body in equilibrium if 2 ~N and 3 ~N act at right angle
- Bcan keep the body in equilibrium if 1 ~N and 2 ~N act at right angle
- Ccannot keep the body in equilibrium
- 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 (c) is correct.
