Can you explain this answer?

Question

Accepted Answer

When a tangent is drawn at any point on field line then that tangent gives the direction of electric field at that point

Answer

Explanation:
Electric field lines are an imaginary construct that represent the direction of the electric field at any given point in space. These lines are always drawn perpendicular to the surface of the charged object. At any point on an electric field line, the tangent to the line is in the direction of the electric field at that point.

Explanation in points:
• Electric field lines represent the direction of the electric field at any given point in space.
• These lines are always drawn perpendicular to the surface of the charged object.
• At any point on an electric field line, the tangent to the line is in the direction of the electric field at that point.
• The electric field is a vector quantity, and its direction is given by the tangent to the field line at that point.
• The electric field is always perpendicular to the equipotential surfaces.
• The electric field lines are closer together where the electric field is stronger and farther apart where the electric field is weaker.
• The curvature of the electric field lines indicates the strength of the electric field at that point.
• The electric field lines always point from a higher potential to a lower potential.
• The electric field lines never cross each other, as this would imply that the electric field has two different directions at the same point.
• The electric field lines always terminate on charges or infinity.
• The electric field lines always start from a positive charge and end at a negative charge.
