As physics

A 2.0 rigid rod with negligible weight is subject to forces in three different ways as shown in diagrams 1-3 below.

diagrams:

1- middle point: 2.0 N
distance on both sides: 1.0 m apart
forces below at the end of each side: 1.0 N

2- distance on both sides: 1.0 m apart
force above at end of side 1: 2.0 N
force below at the end of side 2: 2.0 N

3- distance on both sides: 1.0 m apart
forces below at the end of each side: 2.0 N

For the rod to be in equilibrium which of the diagrams above is /are correct and say why.
