A point charge with charge q₁ = 2.30 μC is held stationary at the origin. A second point charge with charge 92 = -4.90 μC moves from the point (0.140 m, 0) to the point (0.260 m, 0.235 m). Part A How much work is done by the electrostatic force on the moving point charge? Express your answer in joules. ▸ View Available Hint(s) W = ΜΕ ΑΣΦ ? J

Learning Goal: 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 F, electric field Ē, 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. Part B Now find the gravitational potential energy U (z) of the object when it is at an arbitrary height z. Take zero potential to be at 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) = Submit ΨΕ ΑΣΦ Request Answer ?
