The table shows electron transfers during two separate tests. All four objects are initially neutral.
| Test | Electron transfer |
|---|---|
| P | From rod X to cloth A |
| Q | From cloth B to rod Y |
The cloths are removed. Rod X is brought close to rod Y. Which statement correctly links the transfers to the force?
X has an electron excess and Y a deficit, so the rods repel.
X has an electron deficit and Y an excess, so the rods attract.
X has an electron deficit and Y an excess, so the rods repel.
X has an electron excess and Y a deficit, so the rods attract.
