Solve this multiple-choice question and choose the correct option.

Electrostatics and charge motion: If point A is at a lower electric potential than point B, how does an electron between A and B move? Assume the electron is free to move along the line joining A and B with no other forces. Choose the correct option.

Difficulty: Easy

From B to A (toward lower potential)
From A to B (toward higher potential)
Remains at rest
Oscillates randomly

Correct Answer: From A to B (toward higher potential)

Explanation:

ConceptElectric field points from higher potential to lower potential. An electron (negative charge) accelerates opposite to E, i.e., toward higher potential.

Final AnswerFrom A to B (toward higher potential)
