Question

Moira is drawing the electric field lines around a pair of charges. One charge is positive, and the other charge is negative.

A positive and negative sphere next to each other.

How should she draw the field lines?

away from each charge and meeting in the middle
away from each charge and curving away from one another
away from the positive charge and toward the negative charge
away from the negative charge and toward the positive charge

Answer 1

away from the positive charge and toward the negative charge

Electric field lines point in the direction a positive test charge would be pushed: they start on positive charges (point away) and end on negative charges (point toward).
