1. The problem statement, all variables and given/known data X and Y are two uncharged metal spheres on insulating stands, and are in contact with each other. A positively charged rod R is brought close to X. Sphere Y is then physically moved away from X. What are the final charge states of X and Y? 2. Relevant equations N/A 3. The attempt at a solution I think X is negative and Y is positive. Can anyone elaborate on why this may be?
