Experiment 2 - Pair of opposite charges (electric dipole) 1. Place a positive charge on the left side of the grid and a negative charge 7 large grid squares away. 2. Use the voltage sensor to find 5 equipotential surfaces equally spaced apart. Click the pencil icon in the sensor to draw a green equipotential curve wherever you want to draw an equipotential curve. 3. Sketch four electric field lines (in red) along with the equipotential surfaces (in blue)
