A Level Physics PowerPoint Presentation | Forces between charges
Forces between charges;
It applies to point charges a distance ‘r’ apart but can be used for any charged objects as long as they are small in diameter compared to ‘r’ – ‘r’ is then the distance between their centres.
The fact that F is proportional to 1/r2 is called the inverse square law of electrostatics.
