L and K are two conductor tables, L is grounded (his potential is zero). In this situation the scales are balanced. To measure the charged object's potential, it is being connected to K with thin long conduct wire. just L and K are conductors. when the object is connected to K, L and K are...
I didnt get the whole thing with the angles... and I don't care about the mathematical explanations, it's just don't make sense that I go further and there is same force...
Can you explain it little more clearley?

Distance from plane??
When you have infinite plane and you check the electric field in a point near it, you find out that it doesn't depend on the distance of this point from the plane.
Why the distance from the plane does not affect the electric field produced by it??
and if you could give...
