A-LevelPhysicsElectric fieldsOct/Nov 2017Paper 2 Q610 Marks
Two parallel metal plates in a vacuum are separated by a distance of 15mm, as shown in Fig. 6.1. A uniform electric field is produced between the plates by applying a potential difference between them. A particle of mass 1.7 × 10⁻²⁷ kg and charge +1.6 × 10⁻¹⁹C is initially at rest at point A on one plate. The particle is moved by the electric field to point B on the other plate. The particle reaches point B with kinetic energy 2.4 × 10⁻¹⁶ J. [Figure 6.1]
