Question
500V 4sov 00950 120V 600V 250V The grid above is given in units of centimeters. (a) if the diagram above shows equipotential lines from an unknown distribution of charge, indicate by illustration the electric field lines corresponding to the unknown distribution of charge. (S points) fie. draw at least 10 unique E-field lines on the diagram above) (b) If a positive test charge were moved from point (A) to point (B) would the system (field and test charg be doing positive or negative work? Explain. (5 points)Explanation / Answer
For part (a) ,draw electric field lines such that they are perpendicular to equipotential lines shown in the diagram and direction on those lines will be in the direction of decreasing potential.
(b) As going from A to B,potential is decreasing so it is direction of electric field so work done is positive for positive charge
