Electrostatic lines of force are drawn such that they originate from positive charges and terminate on negative charges. They emerge perpendicular to the surface of the charged object and do not intersect each other. The density of lines indicates the strength of the electric field.
No. Lines of the electrostatic field don't intersect. A 'line' of the electrostatic field is an imaginary thing that shows the force on a tiny 'test charge' placed at any point. If two 'lines' intersected, it would mean that a tiny test charge at that point would feel a force in two different directions, and would have a choice of which way to go. But that doesn't happen ... the force at any point in the field is in a single, definite direction.
always towards the charge
Magnetic lines of force are called magnetic field lines.
A magnet with many lines of force refers to a strong magnetic field that is densely packed with magnetic field lines. These field lines represent the pathways along which the magnetic force acts, flowing from the magnet's north pole to its south pole. The density of these lines of force indicates the strength of the magnet's magnetic field.
Electric field lines are drawn with arrows to show the direction of the force that a positive test charge would experience if placed in the field. The direction of the electric field at any point is the direction that a positive test charge would move when placed in the field at that point.

Infinite lines can be drawn from a point
A square by definition has lines of symmetry. Therefore a square cannot be drawn without any lines of symmetry.
5 lines is symmetry
They are perpendicular lines
Through two given lines, there can be either zero, one, or infinitely many lines that can be drawn, depending on their relationship. If the two lines are parallel, no line can pass through both. If they intersect, exactly one line can be drawn through their intersection point. If they are coincident (the same line), then infinitely many lines can be drawn through them.
This diagram is an example. The bolded lines are the lines you should draw._________ __________|/////////////|////////////////||/////////////|////////////////||/////////////|////////////////||/////////////|////////////////||-----------|-------------|Note: The top solid lines should be drawn, and the dashed lines on the bottom would be drawn, also. The slashes are just filling.
the lines of force are not real. these lines of force are imaginary lines. so we can not touch it.
Not normally
