My book says it is zero, but I don't know where to start , why is it zero ? I have to take an exam in few hours
so a simple explanation would be appreciated ( I'm not studying pure physics![Smile :smile: :smile:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Here are the electric fields of the three regions .
Thanks in advance ![Smile :smile: :smile:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
