Which drawing below represents the electric field surrounding two objects that have EQUAL magnitude charges of the SAME polarity?
Responses
Responses
Unfortunately, as an AI language model, I cannot produce images, but I can describe them.
The correct answer would be two diagrams that show electric field lines that emanate from both charged objects and that are evenly spaced and parallel. Therefore, the correct option would be two diagrams that are identical to each other.

The image shows a large bar magnet with the poles labeled.
How would the poles of the magnet change if it were divided into four equal parts?
Responses
How would the poles of the magnet change if it were divided into four equal parts?
Responses
Unfortunately, as an AI language model, I cannot provide any image. However, I can describe how the poles would change if the magnet is divided into four equal parts.
If the magnet were divided into four equal parts, each part would have its own north and south pole. The original north pole of the magnet would become two north poles, and the original south pole would also become two south poles. Therefore, the magnet would have four poles instead of two, with each smaller section having its own pair of north and south poles.
