Equation for Tesla's ****eld

i was interested in simulating intelligent lever and the topic
"leverian physical impacts" came kra****ng on me but as i made the
effort to amortize the force of impact "The Equation for Tesla's
****eld" appeared before me...

What good will binoculars do for Cyclops?
With:
 a=|D[1]|/|D[1]-D[2]|;
 b=|F[2]|/|F[1]-F[2]|;
 c=|D[2]|/|D[1]-D[2]|;
 d=|F[1]|/|F[1]-F[2]|;
 |i| <= 1 and |j| <= 1
And i^2 + j^2 = 1;

|B|   |a b|   |F[1] F[2]|   |i|
| | = |   | x |         | x | |
|H|   |c d|   |D[2] D[1]|   |j|

B is the force at point H from the origin.
