Show that if at some part of a field the lines of force have the from of concentric circles whose centres are at point O (as given in Fig. 3.39), the field intensity at each point in this part of the field should be inversely proportional to the distance from the point O. .

Some electric lines of force are shown in figure. For points a and B

Electric lines of force about negative point charge are

(A) : No two electric lines of force can intersect each other (R ): Tangent at any point of electric line of force gives the direction of electric field.

Electric lines of force are as shown in the figure. Then potential at point P

Assetrion: Electric lines of force never cross each other. Reason: Electric field at a point superimpose to give one resultant electric field

If electric field is uniform, then the electric lines of forces are :

what is the net force on a dipole in a uniform electric field ?

An electron enters an electric field with its velocity in the direction of the electric lines of force. Then

The property of the electric line of force (a) The tangent to the line of force at any point is parallel to the direction of .E. at that point (b) No two lines of force intersect each other
