Draw both the electric field linesn and the equipotential lines of a single negative charge. Pay attention to the direction of the field lines and the space between equipotential lines.

Directions of the fields are indicated on field lines. Why are no directions indicated on equipotential lines?

Given the following system of point charges: a positive point charge +q is placed in the middle, while three negative point charges -q are placed at equal distance from each other and at equal distance R from +q. -9 R +9 -9 Given that q = 13 x 10-9 C and R = 0.6 μm find the work required to construct this system of charges.

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..
