Question

1. if an ion is positively charged, its field lines point away from the ion. this indicates that the ion would repel a positive charge. 1) which model represents the electric field around a negatively charged ion?

Explanation:

Step1: Recall Electric Field Rules

For a positive charge, electric field lines point away. For a negative charge, field lines point toward the charge (since negative charges attract positive test charges, so field lines go into the negative charge).

Step2: Analyze the Options

• The first top - left model (with blue -) has field lines pointing away (like positive charge), so incorrect.
• The top - right model (with blue -) has field lines pointing toward the blue negative charge. This matches the rule for negative charges (field lines point to the negative charge).
• The bottom - left and bottom - right models: We focus on the direction of field lines. The top - right model's field lines are directed towards the negative ion, which is correct for a negative charge's electric field.

Answer:

The top - right graph (the one with the blue negative ion and field lines pointing towards it)
