The cross product of B and E is called the Poynting vector, represented by BXE so BXE = s

basically in cosmic terms

(1/r^3 * 1/r )^0.5 = s

so the resultant force s is
s = 1/r^2

so this resultant is a 1/r^2 force.... and it is directed orthogonal to both E and B

what cosmic force do you know falls off at the square of the distance ?

The Cavendish experiment, performed in 1797–98 by British scientist Henry Cavendish, was the first experiment to measure the force of gravity between masses in the laboratory,[1] and the first to yield accurate values for the gravitational constant. Wiki

By measuring the force between two lead balls, Cavendish measured the relation between the mass of matter and gravity, and so measured the gravitational constant of Newton, G [the two body problem]

The currently accepted value of G = 6.67428 × 10−11 m3 kg−1 s−2.

Marvellous work... but totally misinterpreted.
