The magnitude of the electrostatic force...

The magnitude of the electrostatic force between point charges `q_(1) = 26.0 mu C` and `q_(2) = 47.0 mu C` is initially 5.70 N. The separation is the changed such that the force magnitude is then 0.570 N. (a) What is the ratio of the new separation to the initial separation ? (b) What is the new separation ?
