A small object has charge [itex]Q[/itex]. Charge [itex]q[/itex] is removed from it and placed on a second small object. The two objects are placed [itex]1[/itex] meter apart. For the force that each object exerts on each other to be a maximum, q should be:

2. Relevant equations

[itex]F=\frac{kQ_1Q_2}{r^2}[/itex]

3. The attempt at a solution

The correct answer is [itex]\frac{Q}{2}[/itex] although I can't seem to get to that. Is my formula selection correct. Also, if force is maximum, which value do I cosider it as. Thanks for the guidence in advance.
