WebThe result, div F, is a scalar function of x. Since this definition is coordinate-free, it shows that the divergence is the same in any coordinate system. However it is not often used practically to calculate divergence; when the vector field is given in a coordinate system the coordinate definitions below are much simpler to use. public storage 91604WebHere you have to be careful about Ex (net) and Ey (net) they are the resolved components that is Ey (net)=Ey (from 1st charge)±Ey (from 2nd charge).The sign will depend on directon.If you only have one charge then Ey (net)=Ey (of the charge). In the video Ey= (sin58.1)2.88=2.30N/C but it will get cancelled out by other charge. public storage 92126Weblator is used, however, it is necessary to conduct electric field analysis to determine the electric field. 3-2 Element Discretization to Determine the Maxi-mum Electric Field The finite element method was used for electric field analysis of a parallel plate electrode with a spheroid at its top (see Fig. 1) to determine the maximum electric field public storage 92nd flavelThe electric field is defined at each point in space as the force per unit charge that would be experienced by a vanishingly small positive test charge if held stationary at that point. As the electric field is defined in terms of force, and force is a vector (i.e. having both magnitude and direction), it follows that an electric field is a vector field.
