It is basically because of this; a vector field is a well-defined function, so it cannot have two different values at the same point. Consequently, the lines representing the field cannot cross each other at any given location in space. The TTC should work to remove barriers to transatlantic trade in goods and services and ensure a level playing field as we navigate the digital and green transitions. However, mathematically, two intersecting curves can have the same direction of tangent at their intersection point. In fact, electric fields originate at a positive charge and terminate at a negative charge. As such, the lines are directed away from positively charged source charges and toward negatively charged source charges. Do any field lines cross one another? This could never be the case. In reality, there never was a time when electric fields go to different directions. Electric field lines always point in one direction, at any point. When lines cross, they provide information about the polarity of the electric field at the location on which they are located. Electric field of point charges. Question. 2003-2022 Chegg Inc.
