1. How many protons would be required to make a charge of 5 C?
2. Imagine having a collection of 1 million electrons. What is the total charge (in C) of this?
3. If you have two charges, 10 C and 5 C, separated by a distance of 0.1 m, find the following:
a. the force between these charges
b. whether the charge is attractive or repulsive
c. what types of particles these charges are made of (most likely)
d. what would happen (exactly) to the force between the charges if the distance were tripled
4. What is an electric field, and how does one draw them? (This may be a challenging question.)
5. If two identical charges experience a repulsive force of 100 N, when separated by a distance of 0.01 m, what is the value of each charge? Are the charges made of electrons or protons? How could you tell?
