Answer 2

If you place a positive charge into an electric field, it will move in the direction indicated by the electric field lines.

Step-by-step explanation:

The electric field is directed radially outward from a point charge in all directions. So when the charge is positive, the force it suffers will be parallel to, the electric field, and if it is negative the force will be opposite to the field.
