    1. The problem statement, all variables and given/known data
    Two point charges are separated by 5 cm. The attractive force between them is 16 N. If the two charges attracting each other have equal magnitude, what is the magnitude of each charge?
    Enter a number.
    Coulombs



    2. Relevant equations
    Force =k*(q1*q2/d^2)



    3. The attempt at a solution
    16N=(9*10^9 N*m^2/C^2)(q1*q2/.223 m)
