what do you think you know about physics, physics is the study of matter under the effect of energy, but does this includes solid states bodies, atoms at ground states, object at microscopic size or object moving faster than light? these and more is what prompt me to ask again what is physics?
if the distance between two charges is quadrupled what will happen the force between the charges
The distance between the charges will decrease 16
times, what we need to do is to divide the force by 16. Remembercoulomb force is an inverse square law.
