Uniform electric fields
Dive into the fascinating world of **uniform electric fields**, where the electric push or pull is perfectly consistent! Unlike the variable fields around a single point charge, uniform fields offer a predictable environment, making them crucial for understanding how charged particles behave in devices like cathode ray tubes. Get ready to explore their characteristics, calculations, and the paths particles take within them. This pilot aligns with **Senpai Corner** A Level notes (2025–2027) for topic **18.2**.
Need to know
What you need to know
- E is now also defined by the units Vm -1.
- The equation above can only be used for two charged parallel plates.
- A charged particle will move through an electric field due to a force on it that is caused by said electric field.
- The trajectory, as shown in the diagram above is parabolic.
- The direction of parabola depends on the charged of the particle.
