Which of the following figures CORRECTLY represents the electric field lines due to a negative point charge?
Correct answer: B. B
- A. A
- B. B
- C. C
- D. D
Explanation
All arrows are directed inward toward the negative charge. This is the correct representation because electric field lines terminate on negative charges. The symmetry and inward direction make this the proper diagram.

About Electric Field
An electric field is the force experienced per unit positive test charge, with the field of a point charge given by E = kQ/r² and directed away from positive charges or toward negative charges. Questions involve field lines, superposition and force on a charge, while electric field must be distinguished from electric potential.
