Question
Two point charges $q_1$ and $q_2$ are 3.00 m apart, and their total charge is $20\textrm{ }\mu\textrm{C}$ . (a) If the force of repulsion between them is 0.075N, what are magnitudes of the two charges? (b) If one charge attracts the other with a force of 0.525N, what are the magnitudes of the two charges? Note that you may need to solve a quadratic equation to reach your answer.
1. One charge is $15.0\textrm{ }\mu\textrm{C}$ and the other is $5.01\textrm{ }\mu\textrm{C}$
2. One charge is $35.0\textrm{ }\mu\textrm{C}$ and the other is $-15.0\textrm{ }\mu\textrm{C}$
