Two objects are identical and small enough that their sizes can be ignored relative to the distance between them, which is 0.200 m. In a vacuum, each object carries a different charge, and they at-tract each other with a force of 1.20 N. The objects are brought into contact, so the net charge is shared equally, and then they are returned to their initial positions. Now it is found that the ob-jects repel one another with a force whose magnitude is equal to that of the initial attractive force. What is the initial charge on each object?

Coulumbs law states

that

f=k * q1*q2/r^2

f is clearly given

r is clearly given

k is a constant 8.99*10^9

1.20=8.99*10^9 * q1*q2/.200^2

where do q1 and q2 come into the picture?
