Concept #1: Relationships Between Force, Field, Energy, Potential

Example #1: Potential at Center of Charges in a Square

Practice: A -2C charge lies at rest. a) What is the potential difference between point A, which is 1.5m from the charge, and point B, which is 4m from the charge? b) What would the work on a 4C charge be to move it from A to B?

Practice: 4 identical charges are arranged so that they are evenly spaced in a circle. If the radius of the circle is 10 cm, and the potential at the center of the circle is – 100 V, what is the magnitude of each charge?

Example #2: Potential Difference Between Two Charges

Example #3: Distance to Stop a Point Charge
