On your tracing paper, using a pencil, lightly connect the dots of each set of equal potential points, forming a continuous, smooth line. mark the electric potential value of each such line. ii. consider one of the equipotential lines that you have just mapped. what can you say about the electric potential of each of the points on that line? iii. now, if there were a small positive test charge qt = 1.0 c at some point a on the 3.0 v equipotential line, then how much work would be done by the electric field to move it to another point b on the same equipotential line? iv. if however, our positive test charge qt were at some point a on the 3.0 v equipotential line, the how much work would have to be done by an outfit like fp& l to move the test charge to another point b on the 15.0 v equipotential line? v. remember how the work done by the electric force is defined wa→b = − δue =  fe • d  r ra rb ∫ , (4) where  fe • d  r = fe ( dr) ˆ fe • dr ∧ = fe ( dr) cos ∠bet . (5) using the definition, what must be the orientation of the electric field lines to the equipotential lines? (this is not necessarily a trivial mental exercise! ) vi. what does it mean physically to say that an equipotential line is at 120 v ?

Which of the following statements are true about the electric potential or the electric potential difference? (a) the si unit of the electric potential is volts (v). (b) the electric potential can also be expressed in units of joules. (c) the electric potential produced by a charge at a given location provides a measure of the rate at which charge flows past that point. (d) as a positive charge moves in the direction of an electric field, it gains electric potential. (f) the electric potential difference between two points is the difference in potential energy possessed by another charge at those two points, divided by this charge.
