DrG-Physics · Forces on Charged Particles · SQA Higher revision

A focused single-topic revision companion on Forces on Charged Particles for SQA Higher ‘Particles & Waves’. Covers everything from charges in uniform electric fields through to circular motion in magnetic fields and the linear-accelerator principle.

The DrG-Physics revision companion is not a worksheet. It is a structured exam-thinking guide — built around the way an SQA marker reads your script. Each worked solution leads with the relationship the examiner is looking for, substitutes cleanly, and evaluates with units. Every question carries a marker-aligned command-word tag (CALCULATE · 2 marks · STATE + JUSTIFY) so students learn what kind of answer earns each mark.

WHAT’S INSIDE
• Theory chapter on charges in electric and magnetic fields, with diagrams of accelerating fields, deflection geometry, and the cyclotron principle
• Five SQA-style questions covering acceleration through a pd, electric-field deflection, F = QvB and circular motion, alpha-particle radius calculations, and the linear accelerator
• Each question fully worked with relationship → substitute → evaluate solutions
• Examiner’s Note after every question naming the typical pitfall (e.g. forgetting the 2e charge of the alpha particle)
• Do/Don’t pair to reinforce SQA marking conventions

TWO EDITIONS · ONE DOWNLOAD
