| Abstract: | Introduced is a real function Va(x) which is useful to solve some physical problems. As an applied example, the movement of two suspended balls losing charge slowly is discussed, and the approximate solution (with high accuracy) for the dynamic equation is presented by using the function Va(x). Some interesting properties concerning the balls' movement are given, |
