Can you please help with demonstration 3

Demonstration 3: Assume the value of the electrostatic potential is zero innitely far from any point charge. At each x in the gure on the right indicate with a symbol {3 or 0} your prediction of whether the electrostatic potential is positive, zero, or negative. At which x would a test charge have the highest electrostatic potential energy? How do you know? Only after you have made your predictions. open the simulation: https :theteoloradoedur'simsfhtmb'charges -and-eldsflatesta'charges- and-elds en. html Place two equal positive charges as shown. Use the Sensor to View the vector representing the eld at each of the three points in the diagram on the right. Use the Equipotential meter to examine the potential at the three points. Examine the sign of the potential at the three points. Compare to your predictions and explain any differences. Measure which of the three points has the highest potential, compare to your prediction, and explain any differences
