# Question: Two charges originally separated by a certain distance are moved

Two charges originally separated by a certain distance are moved farther apart until the force between them has decreased by a factor of 10.

(a) Is the new distance (1) less than 10, (2) equal to 10, or (3) greater than 10 times the original distance? Why?

(b) If the original distance was 30 cm, how far apart are the charges?
