Weak and strong interaction are attactive or repulsive force?

[magnetar]

As we know:Gravitation is attractive force, electric force is attractive and repulsive force.

Weak and strong interaction are attractive or repulsive force?

 

[Civilized]

The repulsion/attraction of the strong interactions depends on the color charges of the particles involved, just as the repulsion/attraction of the E&M force depends on the electric charges. Similarly for the weak interactions. Gravity is the only force which is always attractive.
