Asked by John
Two like charges of the same magnitude are 8.0 mm apart. if the force of repulsion they exert upon each other is 4.0 N, what is the magnitude of each charge? (The constant of proportional for the Coulombic force is 9.0 x 10^9 N.m^2/C^2 )

F = k q^2/r^2
so
q = r sqrt (F/k)
r = .008
F = 4
k = 9 * 10^9
so
q = r sqrt (F/k)
r = .008
F = 4
k = 9 * 10^9
