Why is a small nut attracted to a straw whereas it should be repulsed?

[QUOTE="haruspex, post: 6837174, member: 334404"] Since the problem statement only expects you to be able to find the product of the charges, the question setter clearly understood that you cannot find the individual charges in the asymmetric (washer and straw) model. Different discharge rates is a problem, though. You can only find the sum of the ##\sigma## values. With two balloons you can assume the discharge rates are the same, but I am not sure about washer and straw. No, even an uncharged conductor will be attracted because of the induced charge distribution. [/QUOTE]
