Learning Goal:To understand the relationship and differencesbetween electric potential and electric potentialenergy.In this problem we will learn about the relationshipsbetween electric force F, electric fieldĒ,potentialenergy U, and electric potential V. To understandthese concepts, we will first study a system withwhich you are already familiar: the uniformgravitational field.Part BNow find the gravitational potential energy U (z) of the object when it is at an arbitrary height z. Take zero potential to beat position z = 0. Keep in mind that the potential energy is a scalar, not a vector.Express U (2) in terms of m, z, and g.U (z) =SubmitΨΕ ΑΣΦRequest Answer?
