Read each question carefully and answer to the best of your ability. Show all your work for calculation problems.
1. Which of the following statements about electric charge is true?
Electric charge is created or destroyed during interactions.
The elementary unit of charge is the electron.
Like charges attract, and opposite charges repel.
Electric charge is quantized, meaning it exists in discrete units.
2. According to Coulomb's Law, the electrostatic force between two point charges is inversely proportional to the:
magnitude of the charges.
distance between the charges.
square of the distance between the charges.
permittivity of free space.
3. The SI unit of electric charge is the .
4. A material that allows electric charge to move freely through it is called a(n) .
5. The region around an electric charge where another charge would experience a force is known as an electric .
6. State the principle of conservation of electric charge.
7. Describe the difference between charging by conduction and charging by induction.
8. 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 × 10^9 N·m²/C²)
