3. Now, reset the screen, click Grid, and drag two positive charges onto the screen, placing them 1 m apart and find the electric potential at the midpoint between the two. Now take away one of the positive charges (drag it back down in the box at the bottom of the screen) and replace it with a negative charge and find the electric potential at the midpoint between the two. What did you observe for the electric potential in the case with two positive charges vs one positive and one negative charge, respectively
