a. Let the charge at the top also be +q. It is released from rest while the others remain fixed. +q
i. Describe its motion.
When it is far from the others, what is its kinetic energy?
b. Now let the charge at the top be -q, and again it is released from rest.
i. Describe its motion.
ii. What is its maximum kinetic energy?
2) A 1 μF parallel plate capacitor is charged by a 100 V battery. The separation between the plates is slowly reduced until the capacitance becomes 2 μF , while the battery remains connected.
a. How much has the capacitor's stored energy increased?
b. How much additional charge ΔQ has been put on the plates?
c. How much additional energy was added to the system by the battery?
d. Account for the difference between your answers to (a) and (c)
3) Consider a system of three identical parallel plate capacitors (numbered 1, 2, 3) each having a capacitance C = I μF and connected as shown.

a. If 60 V is applied across the terminals of the system and the capacitors become fully charged, how much energy is stored in capacitor $1?
b. The system is now isolated from the charging source, and a slab of dielectric with K. = 2 is slipped between the plates of $1, filling the gap completely. What is the new stored energy in #1?
c. What is the new potential difference across the terminals?
