D. Coulomb Force 1. Open the simulation https://phet.colorado.edu/sims/html/cou ... ulombs-law en.html Select the Macro Scale option. Check the box to show the Force values (on right side).
a. Choose values for q₁, q2, and the separation distance and make note of the magnitude of the force. Now increase the magnitude of q2. How does this affect the magnitude of the force? Does it get larger or smaller? b. Choose values for q₁, q2, and the separation distance. Select charge values so that the charges are of opposite sign. Notice the direction of the force between the charges. c. Now, keeping the separation and magnitude of the charges the same, make the two charges the same sign (ie both positive or both negative). How does the magnitude of the force compare to above? What is the direction of the force now?
