Question

state any four properties of electric lines of force

Answer 1

one do not intersect the other.
from north to south outside
from south to north inside

Answer 2

the properties includes-

1.) they start from  a positive charge and move towards a negative charge.

2.) tangent drawn at any point gives the direction of the electric field at that point

3.)Electric lines of force are closer where the electric field is stronger and the lines are apart  where the electric field is weaker

4.)Electric lines of force do not pass through a conductor.
