Can somebody answer this question? Suppose the electrified

object is like a pear. Or more exactly it is a set of two spherical

segments connected smoothly with a truncated cone. Let the

left segment have R1=20 cm, the right segment R2=5 cm and

the distance between the centers of segments 30 cm. There is

nothing special about this geometry; it is an illustration.

We all known that concentration of charges will be higher on

the right "pole" than on the left "pole". But how many times

larger? Factor of 4? Factor of 16? Neither of the above? Is

there any rule of thumb about this?

The answer will be nearer to 4 than to 16, but it is also well

known that if you wish to solve this problem you must do so

numerically.
