Yes it does. Think of the voltage as an electric field and hence the stronger the electric field (and similarly larger voltage) the stronger it will push charges. Consequently, even more charge will accumulate on both leaves (of the same charge) and hence there will be a stronger "Coulombic" repulsive force between the two leaves, and hence farther ...

An experimentalists answer: Why do same/opposite electric charges repel/attract each other, respectively? Because careful physicists have made an innumerable number of observations and have found that this is what nature does. There is a long history of observations before any theory could be solidified. They observed the behavior of attraction with ...

This equation is said to "reduce to quadratures": you can essentially solve it exactly, in the sense that you get your solution as a well-defined integral. This integral is perfectly fine as a function, and it can be used if you so wish to calculate the solution numerically. Unfortunately, while you can do this integral exactly, the final step requires an ...

For the case of zero initial velocity (the free fall problem) the exact analytic answer for x(t) is shown to be an infinite power series in http://en.wikipedia.org/wiki/Free_fall#Inverse-square_law_gravitational_field. Probably for a nonzero initial velocity x(t) one can work out an answer as an infinite series as well; surely it is not going to be anything ...

He used what is called a torsion balance. His experimental method is outlined very nicely in this video. After Coulomb published the result of his work, however, it was debated as to whether his experiment really did provide enough evidence to support his claim that the force between two point charges really did follow the equation we now call Coulomb's ...
