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

AI Thread Summary
When an uncharged sphere C touches a charged sphere A, charge redistributes between the two spheres. If sphere A is positively charged, sphere C will also become positively charged after contact, and the same applies if A is negatively charged. Since both spheres are identical, the final charge on each can be expressed as a ratio; specifically, the final charge on A will be half of its initial charge. However, it is not possible to calculate the exact final charge without knowing the initial charge value on sphere A. The principle of charge conservation applies, but the specific values cannot be determined without additional information.

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.

No.
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
