Question

1. Rank the potential energies of the four systems of particles shown, from largest to smallest. Include equalities if equal (see figure)

2. A positive charge in a uniform electric field accelerates, gaining 5 J of kinetic energy. How does the charge's potential energy change?

3. A and B are both points on an equipotential surface. What is the potential difference between point A and B?

4. Two point charges are fixed on thex-axis. Imagine moving a positive charge from point P to the origin along the different paths shown in the diagram. For which path would you do the most work? (See figure)
