Question

Three concurrent coplanar forces 1 N, 2 N and 3 N acting along different directions on a body:

• A. Can keep the body in equilibrium if 2 N and 3 N act at right angle
• B. Can keep the body in equilibrium if 1 N and 2 N act at right angle
• C. Cannot keep the body in equilibrium
• D. Can keep the body in equilibrium in 1 N and 3 N act at an acute angle

Answer 1

The correct option is C Cannot keep the body in equilibrium

We can clearly see that the first two forces $1N,2N$ if they are in the same direction, then they would equal to the third force $3N$. But it is given that the three forces are in different directions. So there is no possibility of equilibrium with these forces in different directions.
