A parallel-plate capacitor is made of two square plates 25 cm on
a side and 1.0 mm apart. The capacitor is connected to a 50.0-V
battery. With the battery still connected, the plates are pulled
apart to a separation of 2.00 mm. What are the energies stored in
the capacitor before and after the plates are pulled farther apart?
Why does the energy decrease even though work is done in separating
the plates.

A parallel plate capacitor consists of two square plates, each 2
cm on a side, with a separation of 2 mm. The magnitude of the
charge on each plate is 4 nC. An electron is released from rest at
the negative plate and accelerates towards the positive plate. What
is the magnitude of its velocity when it reaches the positive
plate?

Find capacitance of parallel plate capacitor with square plates.
Length of the side is 10 cm and distance between plates is 2 mm.
Find charge on the plates and electrical energy stored in the
capacitor if it is connected to the battery providing 250 V. Find
capacitance, energy and charge if capacitor filled with dielectric
with K=3 (still connected to the same battery).

4. Two parallel square plates are spaced a quarter of a
millimeter apart. One billion electrons are transferred from one
plate to the other, and an electric field of 10,000 Newtons per
Coulomb results. How big is each square plate on a side? What is
the surface charge density of each square?

Two 2.5-cmcm-diameter-disks spaced 1.5 mmmm apart form a
parallel-plate capacitor. The electric field between the disks is
4.7×105 V/mV/m .
What is the voltage across the capacitor?
How much charge is on each disk?
An electron is launched from the negative plate. It strikes the
positive plate at a speed of 2.0×107 m/sm/s . What was
