Electric field display of two negatively charged bullets

High school physics course focuses on themes about electrical charges and an electric field.

Video format task examples are a great opportunity to understand the topic and to understand what needs to be addressed in the tasks, because while you are watching the video,you can follow the example of the task and you can understand how to properly complete all the given tasks.

The video is quite short, but it covers important information on this subject that will be needed to do the task.

Watch this video about electric field display of two negatively charged bullets and later answer the questions!

Answer the questions:

1. In which direction are the negative power lines directed?

2. Does the two negative charges affect each other intensity line direction?

3. If you have two negative charges, they repels or extremes to each other?

4 . What kind of negatively charged bullets are displayed in the video example?

5. If there would be only one negatively charged bullet, how would the lines be directed?

6. What kind of  negatively charged lines are there in the video? (unsymmetrical or symmetrical?)

7. What does negatively charged  lines do, which are the next after the first line? (do they bend?)

8. What can be determined according to the intensity of the lines?

Answers:

1. It is directed in the negatively charged bullet;

2. Yes, they do affect each others intensity line direction;

3. They repel;

4. They are a point charges;

5. Lines would be directed straight into the bullet;

6. They are symmetrical;

7. They bend;

8. That negatively charged bullets repels.

You have done the task!

Hopefully, now you understand electric field display of two negatively charged bullets ! Now it will be much easier to understand other topics about eletric fields and eletric charges.

To understand this topic even better, I suggest to visit some interactive portals about physics or in your course book.
