Q:
We observe two charges separated by a distance of 1.00 meters. If the distance between the two charges is changed to be half what it was, by what factor would the electric force of between them be changed. That is, what is the ratio of the new force to the old force? (If you have a fraction you will have to enter it in decimile form, for example enter 1/5 as 0.20)
