### Two Body Problem for different Force Laws

I understand that the two body problem is solvable, for any two bodies using the inverse square law, and it is also solvable for the reciprocal law. I understand that the three body problem is not in general solvable, although there are some special cases of the three body problem that are solvable....

### Determining, which electrically charged fluids will sink on an electrically charged sphere?

There is an electrically charged sphere with a significant electrical charge, and in which the mass and radius are such that the gravitational acceleration from the sphere is negligible. Also any tidal forces on the sphere are negligible and the sphere is in a near inertial if not an inertial refere...

### Force between a point and an infinite straight line

How would I find the force law that describes the force between a point and an infinite straight line g(r), given the force law between two points is f(r)? I have found that simply multiplying f(r) by r only produces the force law g(r) when f(r) is an inverse, or reciprocal law, but if f(r) is somet...
