Question

You have a large metal sphere that starts out isolated and has no net charge. Then you bring a positively charged rod near it without touching.
Will there be a force between the sphere and rod?

Draw a qualitative diagram showing the location of the charges in the metal sphere once the rod is brought near.

Answer 1

Answer:

Yes

Explanation:

There will be a force because the large metal sphere is polarized when the rod is placed close to it, this happens because the metal sphere has free electrons and they will be attracted by the positively charged rod, the sphere will remain neutral as a whole (the same number of negative and positive charge), but a portion of the sphere will become more positive and the other more negative, creating this force.
