Based on your experiments with the John Travoltage simulation (PhET), identify the scenarios that are true: (select all that apply) Group of answer choices The negative charge flows from John to the doorknob Not much charge can build up on John's body while his finger is close to the doorknob John must physically touch the doorknob in order for a discharge to occur The larger the charge on John's body, the closer he must be to the doorknob before a discharge occurs
