Two positive charges initially 1 m apart move so that they end up 2 m apart. In the fina configuration, their electric potential energy has... O increased O decreased O remained constant O [It depends on how they moved to their new positions.]

Two -1 C charges are separated by a distance d giving them some electric potential energy. Next they are placed at equal distances from an unknown charge as shown. How does the total potential energy of thi new collection of charge change? -1 C -1C O It increases. It decreases. O It remains the same O It depends on the sign (polarity) of the top charge.

Choose all correct statements about electric fields and/or equipotentials. Electric field lines point away from positive charges. Electric field lines are perpendicular to equipotential curves at any particular point in space. Electric fields are stronger the closer together equipotential curves are in some region of space. Equipotential curves start at positive charge and end at negative charge. | There is no change in the potential energy of an electric charge as it travels along an electric field line. Electric fields are stronger the closer together electric field lines are in some region of space. Electric field lines start at positive charge and end at negative charge. Electric field lines point into negative charges. | There is no change in the potential energy of an electric charge as it travels along an equipotential curve. Electric field lines are parallel to equipotential curves at any particular point in space..
