Unformatted text preview: equipotential surfaces! Electric field lines are always perpendicular to the equipotential surfaces! An electron goes from one equipotential surface to another along one of the four paths shown below. Rank the paths according to the work done by the electric field, from least to greatest. A) 1, 2, 3, 4 B) 4, 3, 2, 1 C) 1, 3, 4 and 2 tie D) 4 and 2 tie, then 3, then 1 E) 4, 3, 1, 2 Calculating electric field from the potential! The electric field in a region around the origin is given by ) ( yj i x C E + = r r where C is a constant. The equipotential surfaces are: A) concentric cylinders with axes along the z axis B) concentric cylinders with axes along the x axis C) concentric spheres centered at the origin D) planes parallel to the xy plane E) planes parallel to the yz plane Electric potential by a continuous charge distribution: thin charged disk...
