    Three concurrent co-planar 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

    Correct Answer: C

    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.
