Useful relationships for solving problems can be found at EQUATIONS.

1. Consider a point charge q = + 50 uC. a) Determine the potential at point X 80 cm away. b)Now determine the potential at point Y 25 cm away. c) What is the potential difference between these two points? How much work will it take to move +70 uC from X to Y? What agent does the work?

2. A flashlight battery is rated at 1.5 V. how much energy does each charge carry in traveling from one terminal to the other?

3. Two point charges +3q and -5q are located a distance L apart. Locate the places on the line connecting them where Vnet = 0. What is the significance of Vnet = 0?
