Question

. Two point charges q1
and q2
are 3.00 m apart, and
their total charge is 20 µC . (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.
