How Does Touching an Uncharged Sphere to a Charged Sphere Affect Their Charges?

[salman213]

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.

[Redbelly98]

qfinal = 1/2 qinitial ??

Yes.

Any way to calculate it? without knowing exactly what the initial q value is on A.

No.

I can provide you with a response to this content. When two identical conducting spheres are brought into contact, the charge on the spheres will redistribute to reach a state of equilibrium. This means that the total charge on the two spheres remains the same, but the distribution of that charge changes.

Specifically, the charge on sphere A will decrease and the charge on sphere C will increase. This is because the electrons, which carry negative charge, will be able to move freely between the two spheres until the charge is evenly distributed.

The exact amount of charge that will transfer between the spheres depends on several factors, including the initial charge on sphere A and the size and material properties of the spheres. Unfortunately, there is no simple ratio or formula to calculate this transfer of charge. It is a complex process that can be accurately determined through experimental measurements.

In summary, when two identical conducting spheres are brought into contact, the charge on the spheres will redistribute to reach a state of equilibrium. The exact amount of charge transferred between the spheres cannot be calculated without experimental data and depends on various factors.
