There are two charged particles that repel each other with a force F. If the charge of one of the particles is doubled and the distance between them is also doubled, then what would the force be and why?
We use formula of the force between two charged particles:
This is where ...
This solution explains how, by altering the charge between two particles and the distance between them, the force also alters between them. This answer in particular addresses what happens to the force between both particles when the charge and distance between them doubles.
