Q1. 1) Does geometry of distribution of multiple charges affect the electric field generated by the charge?
2) Is there any electric field outside a cylindrical conductor within which is a concentric conductor of smaller diameter where the inner conductor is connected to one electrical polarity and outer conductor the other polarity?
3) When a charge that is free to move is released in the presence of an electric field, does it move from a region of high electric potential to a region of low electric potential or vice-versa? Does your reply depend on whether the charge is positive or negative? Why or why not?
