Question

Two points, point 1 and point 2, are located inside a region with an electric field pointing to the left. What is the direction of the electric field?

1) Upwards
2) Downwards
3) To the right
4) To the left

Answer 1

The direction of the electric field at points 1 and 2, which are inside a region where the electric field points to the left, is also to the left.

Step-by-step explanation:

Given the information that the electric field points to the left, it means that this is the direction in which a positive test charge would move. According to our physical conventions, electric field lines are directed away from positive charges and towards negative charges. This convention is based on the behavior of positive charges in an electric field.

If we apply this convention to the scenario provided, since the electric field is said to point to the left, the direction of the electric field at points 1 and 2 is also to the left. This is because the direction of an electric field, is defined as the direction in which a positive test charge would be pushed by the electric force.
