Q. An empty capacitor is connected to a 12.2-V battery and charged up. The capacitor is then disconnected from the battery, and a slab of dielectric material (κ = 2.8) is inserted between the plates. Find the magnitude of the amount by which the potential difference across the plates changes.

Q. A proton is initially at rest at a point where the potential is 510 V. Some time later the proton is at a point where the potential is 186 V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy?
