Electric field lines direct from positive to negative charges

Steps:

• Identify charges: one positive (+), one negative (-).
• Recall: field lines originate at + and terminate at -.
• Direction: lines point away from + toward -.
• Pattern: curved lines bulge outward between charges, no crossings.

Why A is correct:

• Depicts lines starting at + and ending at -, aligning with the rule that field direction follows force on a positive test charge.

Why the others are wrong:

• B: Lines originate from - and end at +, reversing the correct direction.
• C: Lines cross each other, violating the property that field lines never intersect.
• D: Lines are straight and parallel, ignoring the radial nature of point charge fields.

Final answer: A
