Explanation:
Force for electrostatic forces drop/increase quadratically so if the original distance is 8cm, some new distance decrement factor h(just picking a letter) will have to result into a greater force so . Also the force goes with a factor of so so which has to let become . Meaning the new distance is 2cm.
