... the electrons in the neutral pith ball to the ight. This causes the left side of the pith ball to obtain a net positive charge. Since opposite charges attract, the pith ball is attracted to the rod. When they touch, electrons are transferred to the pith ball giving it a net negative charge. Since th ...

... In the previous Sections we introduced the concept of field lines, useful to display the electric field. For the electric potential, we introduce here the concept of equipotential surfaces, i.e. surfaces characterized by the same potential. We notice that field lines always cross equipotential surfa ...

... act on the particle. These forces can be active forces, which tend to set the particle in motion, or they can be reactive forces which are the result of the constraints or supports that tend to prevent motion. To account for all these forces, it may help to trace around the particle's boundary, care ...
