SUMMARY

When an uncharged conducting sphere (C) is touched to a charged conducting sphere (A), charge redistribution occurs. If sphere A is positively charged, sphere C will also become positively charged after contact, and vice versa for negative charge. Due to their identical nature, the final charge on both spheres will be equal, resulting in a final charge of qfinal = 1/2 qinitial for sphere A. This relationship holds true regardless of the initial charge value on sphere A.

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 I am 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.

Yes.
