WebWe can express the electric force in terms of electric field, \vec F = q\vec E F = qE. For a positive q q, the electric field vector points in the same direction as the force vector. The equation for electric field is similar to … WebThe electric field strength is exactly proportional to the number of field lines per unit area, since the magnitude of the electric field for a point charge is. E=k\frac { Q } {r^2}\\ E = k r2∣Q∣. and area is proportional to r2. This pictorial representation, in which field lines represent the direction and their closeness (that is, their ...
WebEquipotential lines are perpendicular to electric field lines in every case. It is important to note that equipotential lines are always perpendicular to electric field lines. No work is required to move a charge along an equipotential, since Δ V = 0. Thus the work is W = –Δ PE = – q Δ V = 0. 19.43 Work is zero if force is perpendicular to motion. WebA useful means of visually representing the vector nature of an electric field is through the use of electric field lines of force. A pattern of several lines are drawn that extend …
