Electric Flux

(True/False) The direction of the flow of the electric field can be determined by the sign of the charge.

The electric field lines passing through a surface area are called:

• Electric Field

• Electric Flux

• Electric Charge

• Electric Lines

When is the Electric Flux zero? (Check all that apply).

• If inside the box there are equal magnitude charges with an opposite sign.

• If one charge magnitude is greater than the other.

• If there are no charges inside the box.

• If the charges are outside the box.

(True/False) An electric flux can be calculated in open and closed surfaces.

• a.

• b.

• c.

• d.

• e.

• a.

• b.

• c.

• d.

• e.

The electric flux through the planar surface above ( positive unit normal to left ) is:

• Positive

• Negative

• Zero

• positive (net outward flux)

• negative (net outward flux).

• positive (net inward flux)

• negative (net inward flux)

• zero
