Question
Statement(A): Negative charges always move from a higher potential to lower potential point
Statement (B): Electric potential is vector.
Statement (B): Electric potential is vector.
✓
Answer
- Both A and B false.
Positive charges move from higher to lower potential whereas negative charges move from lower to higher potential. Hence, A is false. Electric potential does not have direction and is a scalar quantity.
