minutes of videosTwo charges *q*_{1} and *q*_{2} are separated by a distance *d* and exert a force *F* on each other. What is the new force *F ′* , if charge 1 is increased to *q ′*_{1} = 5 *q*_{1}, charge 2 is decreased to *q *′_{2} = *q*_{2 }/ 2, and the distance is decreased to *d *′ = *d */ 2? Choose one.

1. *F *′ = 5/2 *F*

2. *F* ′ = 5/4 *F*

3. *F* ′ = 20 *F*

4. *F* ′ = 25/4 *F*

5. *F* ′ = 50 *F*

6. *F* ′ = 25/2 *F*

7. *F* ′ = 100 *F*

8. *F* ′ = 5 *F*

9. *F* ′ = 25 *F*

10. *F* ' = 10 *F*
