The figure shows several equipotential lines due to some charge distribution (not shown). An equipotential line is a line that connects points with the same electric potential. The value of the potential for each line in volts is shown next to the line. i) Suppose I can place an electron at any of the locations A, B, or C -- where would I place the electron for the system to have the lowest potential energy. ii) If a proton is placed at B (on the 4V line), would it accelerate towards the 2V line or the 6V line? Why? iii) If an electron is placed at B (on the 4V line), would it accelerate towards the 2V line or the 6V line? Why? iv) What is the work done by the electric forces as an electron travels from A to B? v) What is the work done by the electric forces as an electron travels from A to C? vi) Is the electric field higher at A or B?
