To understand the relationship and differences between electric potential and electric potential energy. In this problem we will learn about the relationships between electric force F⃗ , electric field E⃗ , potential energy U, and electric potential V. To understand these concepts, we will first study a system with which you are already familiar: the uniform gravitational field. F⃗ (z) =−mgk^ 1)Now find the gravitational potential energy U(z) of the object when it is at an arbitrary height z. Take...
