Chapter 20, Problem 57P
Two identical small metal spheres initially carry charges q1 and q2. When they’re 1.0 m apart, they experience a 2.5-N attractive force. Then they’re brought together so charge moves from one to the other until they have the same net charge. They’re again placed 1.0 m apart, and now they repel with a 2.5-N force. What were the original charges q1 and q2 ?
