It seems odd that the problem would require advanced knowledge/formulas as this came from a high school physics textbook. Also, I didn't state specifically in my initial post, but the question asks for the new charges on each sphere after they're touched. It also gives a tip (charge resides...

So there's no potential difference when the charges are in equilibrium? But what does this have to do with the question? I have no idea how "potential difference = 0" could affect the final charges of spheres with varying radii.

Cool, I would have to guess that they move because the touching objects desire to have charge spread uniformly across their surfaces. I'd also guess they continue to move until the charges of the two spheres are equal? So you're saying regardless of varying radii sizes, the spheres will reach...

Yeah, and I'm not sure what you mean by the last sentence. I know if the spheres are identical, the charges will become equal when the spheres come into contact. What I'm asking is how do you determine what the new charge on each sphere will be when two non-identical metal spheres (sphere A has...

When the radii of 2 spheres are identical (ie they have identical symmetrical geometries) but have different charges.

Homework Statement Basically, I'm told that two insulated metal spheres, one positively charge (+20uc, sphere A) and one negatively charged (-10 uc, sphere B) come into direct contact (so obviously conduction is the method of charge), and that sphere A's radius is twice the size of sphere...
