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.
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!
