Here, F1 and F2 are the magnitudes of the force between them in free space and in a medium respectively. (c) Potential difference, between any two points, in an electric field is defined as the work done in taking a unit positive charge from one point to the other against the electric field. Dear If q1q2<0, a negative sign from q1q2 will change and . IIT BOOKS DOWNLOAD ; IIT JEE NOTES DOWNLOAD; PHYSICS [PDF]DOWNLOAD ALLEN PHYSICS CHAPTER WISE NOTES AND PROBLEMS WITH SOLUTIONS.
