Please I really need help with my lab. please.We're to use a pHet stimulation: charges and fields. Link: https://phet.colorado.edu/en/simulation/charges-and-fields Instructions: We will be taking satay on how the electric field strength depends on the distance and direction away from the charges. You can use the grid lines to get a sense of distance, but the tape measure (drag it from the right) can provide a more precise value. (After filling in the tables, we will have do graph it and then answer the discussion questions.) please I really need you to help me. Discussion questions:1.) Many relationships in nature follow a power law with integer exponents. Which of the scenarios that you tested have curve fits with exponents that are very close to integers? If the exponents is close to but not exactly, an Integer in your plot what is your interpretation? (Consider how precisely you're able to position the sensor in the stimulation) 2.) Rank the four sceneries according to how rapidly the electric field decreases with distance. Explain your choices. Use the curve fit equations in your plots (with rounded exponents values) to help you with the ranking. 3.) Which scenario(s) closely followed Coulomb's law? What does this make sense? 4.) Describe how the electric field above a line charge (scenario 2) varies along a direction parallel to the line of charges.5.) Describe how the electric field varies as you go in a circle around a dipole.
