Electric field is electric force per unit charge. And the direction of the field is the direction of the electric force it would exert on a positive test charge. Electric field lines reveal information about the direction (and the strength) of an electric field within a region of vectore. If the lines cross each other at a given location then there must be two distinctly different values of electric field with their own individual direction at that given location. This could never be the case. Every single location in vectore has its own electric field Electric Charge and Electric Field Chapter 17 By the end of this chapter you will be able to 1. Sketch the distribution of charges for both conducting and insulating objects in various arrangements. 2. Calculate the number of fundamental units of charge in a particular quanvectory of charge. 3. Determine both the magnitude and direction of the force one charge exerts on another using Coulomb

Notice that as stated above the electric field lines are drawn such that their tangents point in the same direction as the electric field vectors on the left. Because of the nature of electric fields field lines never cross. Also the vectors shrink as you move away from the charge and the electric field lines spread out as you move away from the charge. The vectoring between electric field The direction of an electrical field at a point is the same as the direction of the electrical force acting on a positive test charge at that point. For example if you place a positive test charge in an electric field and the charge moves to the right you know the direction of the electric field in that region points to the right. So recapping to find the total electric field from multiple charges draw the electric field each charge creates at the point where you want to determine the total electric field use this formula to get the magnitude of the contribution from each charge then decide whether those contributions should be positive or negative based not on the sign of the charge but the direction the field is

The electric field for a plane electromagnetic wave traveling in the y direction is shown. Consider a point where E is in the z direction. The B field is Consider a point where E is in the z direction. Electric field emanating from a point positive electric charge suspended over an infinite sheet of conducting material. In electrodynamics circular polarization of an electromagnetic wave is a polarization state in which at each point the electric field of the wave has a constant magnitude but its direction rotates with time at a steady rate in a plane perpendicular to the direction of the wave. Three point charges are located at the corners of an equilateral triangle as in Figure P15.13. Find the magnitude and direction of the net electric force on the 2.00 C charge.
