1. The repulsion law*

F
= L_{0}_{
}Ｍｍｒ
(1)

Where **F ** is the repulsion on either body, **M **
and m
are their mass, **r**
is distance between two centers-of-mass and **Λ**_{0
}is
the repulsion constant.

Suppose repulsion is like gravitation in that they have the same spread velocity.

It can be shown that, the repulsion exerted on or by a body is the same as if the mass of body were concentrated at its center-of-mass no matter what shape and size of the body.

The strength of the repulsion field is

L_{0}^{
}M
ｒ
