Suppose you have two point charges of opposite sign. as you move them farther and farther apart, the potential energy of this system relative to infinity increases? decrease? or stays the same?

When we have two point charges of opposite sign, as we move them farther and farther apart, the potential energy of this system relative to infinity will : increases

when 2 point charges of opposite sign, it will started out as negative. It will got closer and closer to zero as the particles move apart

hope this helps

Ais the answer hope this
