Strong force and the baryon decuplet

MarekS

1. Quarks are confined within a meson or a baryon in a way that the potential energy between them increases as they are torn apart. Yet, the strong force has a limited, relatively short range. How are these 2 statements reconciled?

2. Why is the baryon decuplet in the Eightfold way only comprised of u, d, s quarks. Not the heavier ones c, t, b.

Thank you very much for any input.
