Read each question carefully and provide your best answer. Show all your work for calculations.
1. Which of the following statements about electric charge is true?
Charge is created and destroyed in chemical reactions.
The total charge in an isolated system is conserved.
Electrons carry a positive charge.
Protons carry a negative charge.
2. Coulomb's Law describes the force between two point charges. How does the electrostatic force change if the distance between the charges is doubled?
It is quadrupled.
It is halved.
It is quartered.
It remains the same.
3. The fundamental unit of electric charge is the .
4. Objects with like charges each other, while objects with opposite charges each other.
5. State Coulomb's Law and write its mathematical expression. Define all variables used.
6. Describe the concept of an electric field. How is its direction defined?
7. Two point charges, q1 = +3.0 µC and q2 = -5.0 µC, are separated by a distance of 0.20 m. Calculate the magnitude and direction of the electrostatic force between them. (k = 9.0 x 10^9 N·m²/C²)
