Hey everyone,(adsbygoogle = window.adsbygoogle || []).push({});

There is a question in my book that asks if three particles touch and are then seperated (A- +5q, B - -q, C - 0) what is the net charge? I know the answer is 4q, but it also states the following:

Particle C touches A and is removed. Particle C then touches B and is removed. What is the final charge on C? I got 1.333... but the answer in the back of the book says 1.5. Am I doing something wrong?
