A small positively charged oil droplet is moved from test chamber X to test chamber Y. Its charge does not change.
Each chamber contains two large vertical parallel plates. The droplet is placed in the central uniform region between the plates.
The field lines for both chambers are drawn to the same scale. The table gives the distance between neighbouring field lines at the droplet.
| Test chamber | Charge on left plate | Charge on right plate | Distance between neighbouring field lines at the droplet |
|---|---|---|---|
| X | positive | negative | 6 mm |
| Y | negative | positive | 3 mm |
Which describes the electric force on the droplet in the two chambers?
To the right in X and to the left in Y; greater in Y.
To the left in X and to the right in Y; greater in Y.
To the right in X and to the left in Y; smaller in Y.
To the left in X and to the right in Y; smaller in Y.
