Question

which model represents the electric field around a negatively charged ion?

Explanation:

Step1: Recall electric field rules

Electric field lines for a negative charge point toward the charge (since electric field direction is the force on a positive test charge, so a negative charge attracts positive charges, field lines point inward).

Step2: Analyze each graph

• Top - Left: Arrows point toward the negative charge (inward).
• Top - Right: Arrows point outward (like positive charge, incorrect).
• Bottom - Left: Arrows point outward (incorrect, positive - like).
• Bottom - Right: Arrows point outward (incorrect, positive - like).

So the top - left graph has field lines pointing toward the negative ion, matching the rule.

Answer:
