Read each question carefully and answer to the best of your ability. Show all work for calculation problems.
1. Which of the following statements about electric charges is true?
Like charges attract, opposite charges repel.
Electric charge is not conserved.
The elementary charge is the charge of a proton or electron.
Conductors do not allow charges to move freely.
2. Coulomb's Law describes the force between two point charges. What is the relationship between the force and the distance between the charges?
Directly proportional to distance.
Inversely proportional to distance.
Directly proportional to the square of the distance.
Inversely proportional to the square of the distance.
3. An object that has an equal number of positive and negative charges is said to be .
4. The unit of electric charge is the .
5. Electric field lines originate from charges and terminate on charges.
6. State the principle of conservation of charge.
Match each term on the left with its definition on the right.
7. Electric Field
a. The amount of work needed to move a unit charge from a reference point to a specific point in an electric field.
8. Electric Potential
b. A region around a charged particle or object within which a force would be exerted on other charged particles or objects.
9. Conductor
c. A material that allows electric charges to move freely through it.
10. Two point charges, q1 = +5.0 μC and q2 = -3.0 μC, are separated by a distance of 0.20 m. Calculate the magnitude and direction of the electrostatic force between them. (k = 8.99 x 10^9 N·m²/C²)
