Electric field lines for a static charge:
AStart and end at the same charge
BStart from positive charges and end on negative charges (or infinity); never form closed loops in electrostatics
CForm closed loops, like magnetic field lines
DAre tangential to the velocity vector
Answer & Solution
Correct answer: B. Start from positive charges and end on negative charges (or infinity); never form closed loops in electrostatics
**Electrostatic field lines**: start at +q, end at −q (or extend to infinity). **Open lines**, never closed loops (because ∮ E · dl = 0 for a conservative field). Magnetic field lines, by contrast, ARE closed loops because there are no magnetic monopoles.
