    1. A square of side a has charge + Q and -Q alternating from one corner to the next, as shown. Find the potential energy for the system of charges.

    2. Electric potential is a scalar quantity.

    3. The direction of an electric field is from higher to lower potential.

    4. A charged particle with charge +5.0 uC is initially at rest. It is accelerated through a potential difference of 500 V. What is the kinetic energy of this charged particle?

    5. An electron is initially at rest. It is accelerated through a potential difference of 400 V. What is the kinetic energy of this electron?
