The diagram shows two point charges. Charge A has +4 μC and charge B has +2 μC. They are separated by 0.10 m. What is the direction of the force on charge B due to charge A?
AToward A (attractive)
BAway from A (repulsive)
CZero force
DPerpendicular to the line AB
Explanation
📌 Both charges are positive (like charges). Like charges REPEL. So force on B points AWAY from A. Magnitudes are given: F = kq_A q_B/d² = (8.99×10⁹)(4×10⁻⁶)(2×10⁻⁶)/(0.10)² = 7.19 N, but the question asks direction only. Distractor A: opposite direction; C: force is nonzero; D: force is along line, not perpendicular.
