Which, if any, of the following statements about electric field lines is/are true?
I do not completely understand the movement of particles through an electric field. How to electrons and positrons move? What are the answers to the questions I'm not sure about?
- The electric field is always perpendicular to the surface outside of a conductor. - TRUE
- It is not possible for the electric field to ever be zero. - FALSE
- It is possible for two electric field lines to cross each other. - FALSE
- If an electron were placed on an electric field line, it would move in a direction perpendicular to the field. - NOT SURE
- If a proton were placed on an electric field line, it would move in a direction anti-parallel to the field. - NOT SURE
- If an electron and a positron were in the presence of a very strong electric field, they would move away from each other. - NOT SURE
- Electric field lines originate on positive charge and terminate on negative charge. - TRUE
