1. An electrophorus is charged (as in electrostatics II). It briefly touches one terminal of a capacitor so that a positive charge, +Q, is put on the plate of the capacitor that is connected to the terminal. After the electrophorus is removed, we have; +Q Will any changes take place at other plate (on the right of the diagram)? If so, draw the charge on the following diagram and explain why it appears. Your explanation must include reasons for the sign of any charge that appears and it must say where these electrostatic charges come from. If nothing happens to the other plate then explain why not. +Q

I cant seem to figure this question out. No matter what formula I use I keep getting it wrong. Really need help finding the correct answer. Thanks Below is a transcript of the question incase its hard to see the picture Two particles having charges of 0.550 nCnC and 13.8 nCnC are separated by a distance of 1.30 mm. PART A At what point along the line connecting the two charges is the net electric field due to the two charges equal to zero? Express your answer in meters. CORRECT ANSER IN BOX The electric field is zero at a point = 0.217 mm from 0.550 nCnC . PART B Where would the net electric field be zero if one of the charges were negative? Enter your answer as a distance in meters from the charge initially equal to 0.550 nCnC.
