Each one will experience a force trying to push it away from the other one. If you don't hold onto them, they will move apart.
Two positive charges will repel each other due to the nature of electric charges, as like charges repel according to Coulomb's Law. This results in a force that pushes them apart, which can lead to their acceleration away from one another if they are free to move. This behavior is a fundamental characteristic of electric charges in physics.
