Inverse formula for potential

  1. Dec 17, 2013 #1
    I know potential has an inverse relationship with distance. However what is the equation that deduces this?

    What is the context of your question? What force field are you referring to?

    The question just asks that if a potential is 10 cm from a pt charge and then it is moved to 20 cm no would the potential change?

    So the force is electric force. What is the equation for the force between two charged particles as a function of the distance between them?

    How do you know it is electric force?
