Two uncharged metal spheres X and Y are placed on insulating stands so that they are in contact. A negatively charged plastic rod is then brought close to sphere X. While keeping them on an insulating stand, sphere Y is separated from sphere X. What signs do the charges induced on X and Y have, and how do their magnitudes compare?
- Acharge on X: negative; charge on Y: negative; relative magnitudes: equal
- Bcharge on X: negative; charge on Y: positive; relative magnitudes: different
- Ccharge on X: positive; charge on Y: negative; relative magnitudes: equal
- Dcharge on X: positive; charge on Y: positive; relative magnitudes: different
