Electric Fields

After doing electrostatic forces and understanding of the distance relates to the charges that are located in the different situations. We also learned how these field vectors run with the surfaces of objects and how they interact. In order to understand the way electric field works, the experiments of Active physics will explain the different scenarios the field affect the charge and the forces of electricity. Also being able to know the way to apply qualitative numbers in problems where the charges are different places and use those numbers to come close to the actual numbers.

This is the first simulation of the activity where the charge is dragged to another charged particle and in a image below show our board of answers explaining what is going but a little explanation is that like charges repel from each other.

The charge in the middle is a negative charge and the fields are shown around the charge in uniform circles as seen by the image and the arrows are point toward the charge. With the variables given in the simulation and the lab notebook we were able to find the Q of the charge which was 3.6*10^-7N/C. 

This is the same activity as the one prior but this one has a positive charge in the middle which still show a uniform field around it. Also the charges this time the arrows are pointed away from each other.  

 The third demo of the activity  is a charges passed within two plates of charge and we saw tat when negative the electric field radiates inward and it opposite direction when it is positive. 

 This is the calculations and explanations of the activities from active physics relating to the electric and charges. It explained the different types of the situations the charges can be applied.

This a problem in the lan manual which the charges were placed in different locations of the graph within the negative and positive side of the graph. This is were we used qualitative values to find the electric forces applied and come close to the actual numbers.

With the qualitative values obtained in the problem before, one of the ways to use them to find the forces was to apply it to a spreadsheet and let it do the calculations. 



This is level one of the electric field hockey in which you can see the affect one article like a proton can guide an electron to a specific field by placing them to locations. The interactions between the charges casues the electron to be repelled from the proton and make its way to the goal.

The second level of the field hockey using the same way of the charge interactions between the particles and guide itself through the field.
