Question

question 18 (1 point)
electric field lines near positive point charges
circle clockwise.
circle counter - clockwise.
radiate inward.
radiate outward.

Explanation:

To determine the direction of electric field lines near a positive point charge, we recall the fundamental concept of electric field lines: Electric field lines originate from positive charges and terminate on negative charges. For a positive point charge, the electric field lines radiate outward (away from the charge) because positive charges are sources of electric field. Options about circular motion (clockwise/counter - clockwise) are incorrect as electric field lines for point charges are radial, not circular. The option "radiate inward" is for negative point charges (where field lines terminate on the charge).

Answer:

D. radiate outward.
