Example Question #11 : Electric Potential Energy
If a 
In this question, we're given the charge of a particle, the distance that it travels, and the electric field within which this movement occurs. We're asked to find the magnitude of the change in electrical potential energy that this particle undergoes.
We can begin this problem by writing an expression for the electric potential energy.
Since we have the particle's charge, but not its electric potential, we need to find a way to obtain this term. To do this, we can make use of the distance the particle travels, as well as the electric field.
Combining these expressions, we can obtain our answer.
