Answer: An object with a +3 C charge at a distance of 2 cm.

Reason: Coulomb's law gives force magnitude ∝ |q1·q2|/r^2. Only opposite charges produce attraction, so ignore the negative charges (they repel). Compare the two +3 C cases:
- At 2 cm: 9/(2^2) = 9/4 = 2.25 (relative units)
- At 5 cm: 9/(5^2) = 9/25 = 0.36

The +3 C at 2 cm gives the largest attractive force.
