Question

Which statement is the correct representation of these electric field lines?

A.Both plates are negatively charged.

B.Both plates are neutral.

C.Plate A is negatively charged and plate B is positively charged.

D.Plate A is positively charged and plate B is negatively charged.

E.Both plates are positively charged.

Answer 1

c . plate a is negatively charged and plate b is positively charged

Answer 2

C. Plate A is negatively charged and plate B is positively charged.

Step-by-step explanation:

The direction of the lines of an electric field represents the direction to which a positive test charge placed in that field would move. Therefore, since positive charges are repelled by positive charges and attracted by negative charges, this means that:

- Electric field lines point away from positive charges, and

- Electric field lines point towards negative charges

In the figure in the problem, we see that electric field lines go away from plate B and towards plate A. This means that:

- Plate B is positively charged

- Plate A is negatively charged
