Which one of the following is not a property of electric field lines?a...
Each location in space has its own specific value of electric field strength and direction. If two electric field lines were to intersect at a point, it would mean that there are two different values of electric field at that single point, each with its own direction. This is not possible.

Which one of the following is not a property of electric field lines?a...
Introduction
Electric field lines are used to visualize the electric field around a charged object. They are a convenient way to represent the direction and strength of the electric field. However, not all properties commonly associated with electric field lines are true. In this case, option A states that two electric field lines always intersect, which is not correct.
Explanation
Property 1: Electric field lines never intersect
Electric field lines never intersect each other. If they were to intersect, it would imply that at the point of intersection, there would be two different directions for the electric field, which is not possible. The direction of the electric field at any point is uniquely determined by the charge distribution in that region.
Property 2: Electric field lines always begin on positive charges and end on negative charges
This property is true. Electric field lines originate from positive charges and terminate on negative charges. This is because positive charges repel each other and negative charges repel each other, while positive and negative charges attract each other.
Property 3: Electric field lines do not start or stop midway
This property is true. Electric field lines always begin on a positive charge and end on a negative charge. They do not start or stop midway as there are no isolated electric charges in space. Electric field lines are always closed loops or extend to infinity.
Property 4: Electric field lines are perpendicular to the surface of a charged conductor
This property is true. Electric field lines are always perpendicular to the surface of a charged conductor. This is because the electric field inside a conductor is zero, and any excess charge resides on the surface.
Conclusion
Among the given options, property A is not true. Electric field lines do not intersect each other. They always begin on a positive charge and end on a negative charge, do not start or stop midway, and are perpendicular to the surface of a charged conductor. Understanding these properties helps in visualizing and understanding the behavior of electric fields.
