The area vector for the surface bounded by the loop is perpendicular to surface.
The magnitude of the area vector is equal to the area of the loop and is perpendicular to the surface.
The loop shown at right has an area A. a. The loop is held to the right of a positive point charge as shown.
i. Draw and label an area vector for the surface bounded by the loop.
ii. Sketch electric field lines to represent the electric field due to the charge.
iii. Is the electric flux through the loop due to the charge positive, negative, or zero? Explain your reasoning.
