Question: Explain why two electrostatic field lines never cross each other at any point?

Explanation:

Electrostatic field lines are imaginary line which indicates the direction of electric field at any point and direction is along the tangent of the field lines. If two line corss at any point that means for the particular point the line can represent two different direction of field and which is not possible [For a particular point the direction of field is unique]. Thats why two field lines never cross each other at any point.

N.B: Direction of field line from a positive charge paricle is away from the particle and direction of field line for negative charge particle is towards the particle.
