Procedure:

Using the simulation provided (https://phet.colorado.edu/sims/html/charges-and-fields/latest/charges-and-fields_en.html) a single positive nano-coulomb charge is placed near the center of the screen. The voltage is recorded using the meter provided in the simulation and is measured in the bottom right corner. Then again using the meter provided the voltage is measured in the center directly on top of the positive nano-coulomb charge and recorded.

A single positive nano-coulomb charge is placed on the center and using the tape measure provided in the simulation the distance from the charge to the equipotential sensor is measured and recorded. The voltage is measured and recorded on the equipotential sensor attached to the positively charged nano-coulomb. ADD Screenshots

Results:

Voltage in the bottom right corner: 2.35 V

Voltage recorded at the center of the positive charge: 810.0 V

Distance from the charge to the equipotential sensor: 30.9 cm

Voltage recorded on the equipotential sensor: 54.0 V
