1 Consider the four field patterns shown. Assuming there are no charges in the regions shown, which of the patterns represent a possible equipotential lines: 1) A 2) B 3) C 4) D All of the charges shown are of equal magnitude. What is the electric potential V at the origin? 1. zero 2. positive 3. negative 4. cannot be determined All of the charges shown are of equal magnitude. What is the electric potential V at the origin? 1. zero 2. positive 3. negative 4. cannot be determined A solid spherical conductor is given a net nonzero charge. The electrostatic potential of the conductor is 1. largest at the center. 2. largest on the surface. 3. largest somewhere between center and surface. 4. constant throughout the volume.

2 A parallel-plate capacitor is attached to a battery that maintains a constant potential difference V between the plates. While the battery is still connected, a glass slab is inserted so as to just fill the space between the plates. The stored energy
