A-LevelPhysicsElectric fieldsOct/Nov 2021Paper 2 Q214 Marks
A charged oil drop is in a vacuum between two horizontal metal plates. A uniform electric field is produced between the plates by applying a potential difference of 1340 V across them, as shown in [Figure 2.1]. The separation of the plates is 1.4 × 10⁻² m. The oil drop of weight 4.6 × 10⁻¹⁴ N remains stationary at a point mid-way between the plates.
