A body is in equilibrium under the action of three forces \(\vec{F}_1, \vec{F}_2\) and \(\vec{F}_3\).
Then choose the wrong statement among the following :
1
\(\vec{F}_1 + \vec{F}_2 +\vec{F}_3 = 0\)
2
\(|F_1 - F_2|\le F_3 \le |F_1 + F_2|\)
3
\(\vec{F}_1, \vec{F}_2\) and \(\vec{F}_3\) can be represented by the three sides of a triangle
4
\(F_1+F_2+F_3=0\)
