A factory tests two electrostatic paint sprayers. Both give every droplet a positive charge, and both spray towards identical negatively charged panels.
The table shows the results.
| Sprayer | Mass sprayed in g | Mass deposited in g |
|---|---|---|
| P | 250 | 200 |
| Q | 300 | 225 |
Which conclusion is supported?
Q deposits a greater percentage; both sprays experience attraction towards the panels.
P deposits a greater percentage; both sprays experience attraction towards the panels.
P deposits a greater percentage; both sprays experience repulsion away from the panels.
Q deposits a greater percentage; both sprays experience repulsion away from the panels.
