## Physics for Scientists and Engineers: A Strategic Approach with Modern Physics (4th Edition)

$E_3 = E_4 \gt E_2 \gt E_1$
$E_3 = E_4 \gt E_2 \gt E_1$ When the electric field lines are closer together, it shows that the electric field is stronger. When the electric field lines are spaced farther apart, it shows that the electric field is weaker.
