The properties of electric lines of force:

1. *Continuous Curves*: Electric lines of force are continuous, smooth curves that emerge from positive charges and enter negative charges.

2. *No Intersection*: Lines of force never intersect each other, as it would imply two different directions of the electric field at a single point.

3. *Tangent to Field*: The lines of force are tangent to the electric field at every point, indicating the direction of the field.

4. *Diverge from Positive Charges*: Lines of force diverge from positive charges, indicating repulsion.

5. *Converge to Negative Charges*: Lines of force converge to negative charges, indicating attraction.

6. *Density Relates to Field Strength*: The density of lines of force in a region is proportional to the electric field strength in that region.

7. *No Lines of Force Inside Conductors*: There are no lines of force inside conductors, as the electric field is zero inside a conductor.

8. *Lines of Force are Closed Loops*: For a closed system, lines of force form closed loops, starting and ending on charges.

9. *Direction of Lines of Force*: The direction of lines of force is from positive to negative charges outside a conductor and from negative to positive charges inside a conductor.

10. *Electric Field Intensity*: The electric field intensity (E) is proportional to the density of lines of force.

These properties help visualize and understand the behavior of electric fields and charges.
