PROBLEM SOLVING TACTICS
Tactic 1: Electric Potential Encrypt Work Dolled a Field An electric potential energy is associated with a system of campaniles as a whole. However. you will see -emirates (starting with Sample that associate it with only one panic within a system For example. you might read An electron in an electric field has a potential energy of Such statements are often acceptable but you should always keep in mind that the potential energy is actually associated with a system-here the electron plus the charged campaniles that set up the electric field. Also keep in mind that it makes sense to assign a particular potential energy value such as 10-7 J here, to a panic or even a system only if the reference potential energy value is known When the potential energy is associated with only one panic within a system you often will read that work is done on the particle by the electric field What is meant is that work is done by the force on the particle due to the charges that set up the field.
