The discussion revolves around an experiment involving two identical metal balls, one with a known charge and the other initially neutral. The scenario explores the nature of the electric force between the two balls after they have been brought into contact and then separated.
The discussion is ongoing, with participants seeking clarification on the behavior of charges when the balls are in contact. Some participants express uncertainty about the nature of the force, considering both repulsion and the possibility of zero force, while others prompt further exploration of the underlying concepts.
There is a lack of consensus on the interpretation of the charge interactions, and the original poster's understanding of the concepts appears to be developing. The discussion is framed within the context of homework help, emphasizing the need for conceptual understanding rather than direct answers.
Okay, thanks for replying! Its either between repulsive or zero. It cannot be attractive since both charges aren't opposite. I know its repulsive as the correct answer but wouldn't it be zero since ball b is neutral charged and ball a is positive because for attractive both charges got to be opposite to each other, repulsive they got to be same since its positive and zero how would it be repulsive?tiny-tim said:hi danish1991! welcome to pf!
what happens to the charge when the metal balls are in contact?
tell us what you think, and why, and then we'll comment!
