# Homework Help: pre ap physics

Posted by Angela here again on Sunday, February 27, 2011 at 8:13pm.

** When s conducting sphere is charged positively, initially the charge is deposited on the left side. However, due to the sphere's conducting nature, the charge spreads uniformly throughout the surface of the sphere. Charge is uniformly distributed because: **

A. charged atoms at the location of the charge distribute throughout the surface

B. excess protons move at the location of the charge to rest

C. excess electrons within the sphere move toward excess protons

D. excess charge within the sphere moves out into the ground from the surface by grounding to reduce charge buildup

---------------------------------------

Here is what I got from the question: The sphere must be made of a conducting material, such as a metal. The question must be asking how a conductor works. The pictorial diagram would be:
+ --> a sphere *shown as ()* --> (+)

I do not know what the answer is; however, I think that since a conductor is contains free charged particles to carry the electrical charge across it, C and D must not be the answers to the question.

Overall, I think that A may be the best answer.

All help is appreciated. =)

No, atoms don't move and redistribute themselves. THe excess charge distributes evenly because the charges repel each other, and move away from one another equally.

None of the answers are correct, and frankly, not even close.
