The electric potential difference A V, also called voltage, is expressed in terms of the electric field as follows AV = | Edr where, a is the initial position and b is the final position. If an electric field in a region in space is defined as E= - 2Br? where B is just a constant without an arbitrary value. What is the electric potential difference from position 0 to R? AV = -1- B)ar? 1 Br2 AV = AV = Br3

The electric field in a region of space has the components Ey = Ez = 0 and Ex = (4.00 N/C · m) x. Point A is on the y axis at y = 3.60 m, and Point B is on the x axis at x = 4.40 m. What is the potential difference between VB − and VA?
