Zero Point
What it is:
Zero Point is the point of equivalence of the forces acting on each other of two objects(Gravity and EM). This is where the forces are equal if they were acting on a piece of bread, for instance. If the masses/charges are equal, the Zero Point of the force is directly in the middle, but if it is lopsided, the Zero Point is closer to the lesser mass/charge, due to the inverse square law.
Solving for it:
The basic equations to solve for Zero Point, where:
[tex]M[/tex] is the greater mass.
[tex]Q[/tex] is the greater charge.
[tex]q[/tex] is the lesser charge.
[tex]m[/tex] is the lesser mass(of course, none of this is needed when the masses are equal)
[tex]d[/tex] is the total distance in between the two bodies.
[tex]r_1[/tex] is the distance of M(or Q) from the Zero Point.
[tex]r_2[/tex] is the distance of m(or q) from the Zero Point.
Equations:
Gravity-
[tex]r_1=\frac{Md - Mr_1}{m}[/tex]
[tex]r_2=\frac{md - mr_2}{M}[/tex]
Electromagnetism-
[tex]r_1=\frac{Qd - Qr_1}{q}[/tex]
[tex]r_2=\frac{qd - qr_2}{Q}[/tex]
To solve for the Mass(or Charge)-
[tex]M=m(\frac{r_1}{r_2})[/tex]
[tex]Q=q(\frac{r_1}{r_2})[/tex]
[tex]m=M(\frac{r_2}{r_1})[/tex]
[tex]q=Q(\frac{r_2}{r_1})[/tex]
