The document outlines 7 problems related to electric force and fields. The problems involve: 1) explaining the attraction between a charged rod and neutral paper, 2) comparing Coulomb's and Newton's laws of gravitation, 3) explaining why test charges used to measure electric fields must be small, 4) drawing electric field lines between two negative charges, 5) explaining why electric field lines can't cross, 6) calculating the net force on positive charges at the corners of an equilateral triangle, and 7) calculating the electric field at a corner of a square with differing corner charges.
