Why the inner component is not experienced eletrical force from the outter?

Click For Summary
SUMMARY

The discussion centers on the phenomenon where the inner component of a solid conducting sphere does not experience an electrical force from the outer component, as explained by Gauss's law. The key points include the symmetry of the sphere, the growth of surface area with radius (r²), and the inverse square law governing electrical forces (1/r²). These factors lead to the cancellation of forces acting on the inner component due to geometric considerations. A complete mathematical proof is suggested to be posted in a dedicated homework forum.

If u have conducting spherical which is not hollow. We know from Gauss law that the outter component is experienced electrical force from the inner component. But why the inner isn't experienced the force from the outter. Please show and proof it in mathemetic and describe in the qualitative way. I really want to know this fact. Thank you very much

The qualitative answer lies in the geometry of the sphere and the inverse square law for electrical force:

a)the sphere is symmetric in all directions.
b)surface area growth of the sphere as you increase the radius goes as r^2.
c) force of electrical forces goes as 1/r^2

So the forces are there, they just cancel each other out geometrically.

This is not the full mathematical proof; if this is a homework question then post in the homework forum.
