DUE IN 30 MINUTES. Please Answer it with GRESA Format (Given, Required, Equation, Solution, and Answer). Please also include the screenshots. Thank you!
General Instruction: Answer the questions as concisely as possible. Write in complete sentences and avoid any grammar shortcuts or nonconventional lingos. Refer to the rubrics for a more detailed scoring regarding verbal answers. As for problem-solving, answer using GRESA, complete all the necessary units, preserve as much as four decimal places until the final answer, and round off the final answer to the nearest two decimal places.

2. Choose Macro.
3. Take a few minutes to familiarize yourself with the simulation. Once you are somewhat satisfied your primal desires to change things, follow along with the questions below.
I. Interact on the simulation above: Click the macro scale, then follow these guide questions. Copy the questions to MS Word and bold your answers so your teacher could distinguish it from the questions. Screen capture your answers, then paste it here.
1. Start by placing the charges to 4cm and 6cm. Set their charges to zero.
2. Create a setup where in you can have a resultant electric force that falls within the range of the following:
a. zero Newton
b. between 100-200N
c. between 200-300N
d. between 500-600N
e. between 900-1000N
3. Screenshot each scenario. Place it on MS Word.
4. Verify your simulation by solving for the electric force, using the values you have set (the charges and distance).
II. Perform the activity below. Write it on a clean sheet of paper.
1. Pick the first eight letters of your name (example: R, O, N, M, A, R,C, C)
2. Obtain the numerical equivalent of the letters (their position on the alphabet) (example: R=18, O=15, N=14, etc)
3. Pair any of the two numbers. This will serve as your paired charges. There should be pairs of two positive charges, two negative charges, and two unlike charges. (example: R=18 and O=15, so +15C and +18C)
4. Pick any arbitrary SI prefix for each pair (example: for the first pair, nano, so +15nC and +18nC). You cannot have the same SI prefix for all pairs. Each pair should have a unique SI prefix.
5. Set the distance as 50m, with a multiplier based on the alphabet order of the first letter of your first name (example: R is 18, so 50x10^18 m). Use this distance to all of your charge pairs.
6. Solve the value of the electrical force for each pair.
