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 B's.
Homework Equations
Not too sure, I know charge usually just reaches an equilibrium when the spheres are identical. A guess would be they both end up at +5 uc but I know that's wrong.
Ra = 2 Rb (lol)
The Attempt at a Solution
Unsure as to how to even start unfortunately. The big question is how the doubled radius on sphere A affects the flow of charge from sphere A to sphere B. This has been bothering me for a few weeks now; help would be appreciated!
