The electric field in the xy-plane due to an infinite line of charge along the z-axis is a gradient field with a potential function v(x, y)equalsc ln (startfraction r 0 over startroot x squared plus y squared endroot endfraction ), where cgreater than0 is a constant and r 0 is a reference distance at which the potential is assumed to be 0. use this information to answer parts a through c.. find the components of the elactric field in the x-and y-directions, where ex. y)vx, y). choose the correct answar below where c> 0 is a constant and ro is a reference distance at which the potential is assumed to be 0. use this information to a. (x. y) cro ob. e- (x. y) o c. (x y) (x y)
