## Homework Statement

You remove two socks from a hot dryer and find that they repel with force of 0.002 N when they’re 1 cm apart. If they have equal charges, and you separate the socks until they’re 5 cm apart, what force will each sock exert on the other? Round the answer to 3 significant digits.

## Homework Equations

F=8.9*10^9(q1)(q2) / r^2

## The Attempt at a Solution

Ive been working on this for over an hour and am frieking out! First I try to solve for the two charges, using .1 (1cm-converted to meter). I know that once I get this, I can use it to change .1 to .5 and solve for F. Problem is I have been having trouble solving for Q!!! which leaves me stuck in the begining.

Please please help, Ive got a midterm in the morning.
