Vedclass · Answer

(C) Properties of electric lines of force are as follows:$1$. Electric lines of force are imaginary lines used to represent the electric field.$2$. They originate from a positive charge and terminate on a negative charge.$3$. $A$ tangent drawn at any point on the line of force gives the direction of the electric field at that point.$4$. Two electric lines of force can never intersect each other because if they did,there would be two directions of the electric field at the point of intersection,which is physically impossible.$5$. The density of electric lines of force is directly proportional to the magnitude of the electric field intensity. Therefore,where lines are crowded,the field is strong,and where they are sparse,the field is weak.$6$. There are no electric lines of force inside a conductor in electrostatic equilibrium.Thus,statement $C$ is correct.
