6. What happens to the magnitude of the electric force between two opposite charges if the magnitude of each charge is halved and the distance between their centers is halved?
- A. It is doubled.
- B. It is quadrupled.
- C. It is halved.
- D. It remains the same.
Correct Answer: D
The electric force between two particles with charges of q1 and q2, separated by a distance r, is given by the following equation:
If the magnitude of each charge is halved and the distance between their centers is halved, then the electric force will be
The magnitude of the electric force remains the same.
