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

Q91 / 160 · JIPMER 2012 · Physics

Three concurrent co-planar forces $1 \mathrm{~N}, 2 \mathrm{~N}$ 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
Correct answer
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

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.

Hence, the correct answer is option: 'C'.
