1. The problem statement, all variables and given/known data It is not an actual questions, Just misconceptions For example, Lets find the work done over a distance in an electric field 2. Relevant equations v = PE/q E = F/q F = k q1 q2 /r^2 W = fd 3. The attempt at a solution I didn't study calculus yet but I am going to because I need to get to know these equations. I know that I can't use the formula w = f d because obviously the f varies if I don't have a uniform EF these equations only take place when the electric field is constant otherwise I need to use calculus to find the equation because the forces varies with distance. So in V = PE/C I can't just substitute PE with F d... so if you are able to put the proof of V = kq/r (If it is related to calculus) that would be great so I can check it when I am done with calculus.
