Two identical small metal spheres initially carry charges 푞1and 푞2. 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 푞1and 푞2?

Two conducting spheres have identical radii. Initially they have charges of opposite sign and unequal magnitudes with the magnitude of the positive charge larger than the magnitude of the negative charge. They attract each other with a force of 0.269 N when separated by 0.4 m. The spheres are suddenly connected by a thin conducting wire, which is then removed. Now the spheres repel each other with a force of 0.024 N. What is the magnitude of the positive charge?...
