The knot at the junction is in equilibrium under the influence of four forces acting on it. The F force acts from above on the left at an angle of A degrees with the horizontal. The 5.1 N force acts from above on the right at an angle of 49 degrees with the horizontal. The 5.3 N force acts from below on the right at an angle of 42 degrees with the horizontal. The 5.9 N force acts from below on the left at an angle of 45 degrees with the horizontal.
a. What is the magnitude of the force F in Newtons?
b. What is the angle A of the force F?

This is a serious question beyond my ability to fully think through with mathematical rigor and design an experimental proof. I did what I could, and got nowhere. Unfortunately, I could not disprove this idea.

Electrical dipole moments attract each other. Could gravity just be the collective dipole moments of matter? If you sum all the dipole moments in an atom, is the sum of their forces roughly equivalent to the gravitational force of the atom?

This was a science type of program, maybe Horizon or a long news clip. A good few years ago but the impression has stuck. It was like an Ant coloney, with men climing wooden ladders hundreds of feet tall to earn money, per basket. Some payed diggers, others worked for diggers. Does anyone remember anything about it.
