Final answer:
The statement about electric-field lines from a positive point charge spreading out radially and pointing outward is true according to the principles of electrostatics.
Step-by-step explanation:
The statement is true: The electric-field lines from a positive point charge indeed spread out radially and point outward from the charge. This is a fundamental concept in electrostatics, taught in physics education at various levels. The electric field lines are used to visually represent the direction and relative strength of the electric field around a charged object. Since like charges repel, the field lines for a positive charge are directed away from the charge, symbolizing the repulsive force exerted by the charge on other positive charges.
