Question

when two ions are near each other, their electric fields interact. this model shows the electric field between two positive ions. complete the sentences to describe the model. because the two ions have the same charge, the ions each other. as a result, the electric field lines between them. attract repel

Explanation:

Step1: Analyze charge interaction

Like charges (both positive or both negative) repel each other. Here, both ions are positive (same charge), so they repel.

Step2: Analyze electric field lines

When two positive charges repel, the electric field lines between them do not connect (they "bend" away from each other, showing repulsion). So the ions repel, and the field lines between them repel (or are pushed apart, not attracting).

Answer:

First blank (action between ions): repel
Second blank (field lines behavior): repel (or show repulsion, but based on options, for the ion interaction: repel, and for field lines - they are pushed apart, but the first drop - down after "ions" is to choose repel. So filling:
Because the two ions have the same charge, the ions \(\boldsymbol{\text{repel}}\) each other. As a result, the electric field lines between them (the behavior, but the first blank here is the ion interaction: repel. The options for the ion action are attract/repel, so repel.
