Question

If a suspended object A is attracted to a charged object B, can we conclude that A is charged?

Answer 1

A is charged right? since only unlike charges can attract?

Answer 2

no, you can't.

Answer 3

so...im right?

Answer 4

rub a balloon on the cat. cat and balloon become charged. but the balloon still sticks to your neutral head.

Answer 5

so there is still attraction in neutral?

Answer 6

no. two neutral (uncharged ) objects won't be attracted... charged objects have a field, and that field causes either charge separation or polarization in neutral objects, effectively given them a temporary (induced) charge.

Answer 7

ahh that makes sense
