Two small conducting spheres of equal radius have charges `+ 10 muC` and `-20 muC` respectively and placed at a distance R from each other. They experience force `F_(1)`. If they are brought in contact and separated to the same distance, they experience force `F_(2)`. The ratio of `F_(1)` to `F_(2)` is
