Read each question carefully and provide accurate answers. Show all your work for calculation problems.
1. What happens to the electric force between two charged objects if the distance between them is doubled?
It doubles
It halves
It becomes four times stronger
It becomes four times weaker
2. Which of the following statements is true regarding electric charges?
Like charges attract, opposite charges repel
Like charges repel, opposite charges attract
All charges attract each other
All charges repel each other
3. Coulomb's Law states that the electric force between two point charges is directly proportional to the product of their magnitudes and inversely proportional to the square of the between them.
4. The constant of proportionality in Coulomb's Law is known as Coulomb's and has a value of approximately 9 x 10^9 Nm²/C².
5. Explain the difference between a conductor and an insulator in terms of electric charge movement.
6. Two point charges, q1 = +3.0 μC and q2 = -2.0 μC, are separated by a distance of 0.50 m. Calculate the magnitude of the electric force between them. Is the force attractive or repulsive?
7. Electric field lines originate from positive charges and terminate on negative charges.
