1. If you have two identical conducting spheres A and C. A carries a charge and C is uncharged. Sphere C is touched to A. How does the charge change on A? 3. I know since C was initially uncharged, after it touched A it becomes charged. IF A was positively charged C would become positively charged as well. if A was negative C would become negative. But since they are identical spheres im guessing there is some relation I should know in terms of a ratio of how much charge A will lose? I have no idea what that is? Is tehre such a ratio that since A is identical to C that after C touched A qinitial on A becomes FOR EXAMPLE qfinal = 1/2 qinitial ?? Any way to calculate it? without knowing exactly what the initial q value is on A.
