Why are electric field lines always crossing equipotential lines at right angles? Can somebody please explain this to me? Thanks ![Smile :smile: :smile:](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)

Electric Field Lines are a graphical representation of the direction and magnitude of an electric field. They are used to visualize the electric field around a charged object.
Electric Field Lines are drawn in such a way that the tangent to the line at any point gives the direction of the electric field at that point. They are drawn in a way that shows the direction of the electric field from positive charges to negative charges.
This is because electric field lines are always perpendicular to the surface of a conductor. This is due to the fact that electric charges accumulate on the surface of a conductor and create an electric field that is perpendicular to the surface.
Near a point charge, Electric Field Lines are radially symmetric and point away from a positive charge and towards a negative charge. The density of the lines is inversely proportional to the distance from the point charge.
No, Electric Field Lines cannot cross each other. This is because electric field is a vector quantity and can have only one direction at a given point. Therefore, the lines must always be tangent to each other and cannot intersect.
