Assertion: Electric lines of force never cross each other.
Reason: Electric field at a point superimpose to give one resultant electric field
In above question a statement of assertion is followed by statement of reason mark the correct choice.
Reason: Electric field at a point superimpose to give one resultant electric field
In above question a statement of assertion is followed by statement of reason mark the correct choice.
View answer and explanation
Correct option: B
If both assertion and reason are true and reason is not the correct explanation of assertion
Option B is correct because both the assertion and the reason are true, but the reason doesn't directly explain why electric field lines don't cross. The non-crossing is due to the uniqueness of the electric field direction at any point.

Assertion:- Electric field lines do not cut at any point.
Reason:- At any point, there is only one direction of electric field. Statement-I: A positive point charge is brought in an electric field, the electric field at neary by point will increase
Statement-II: Electric field produced by charge may favour the existing electric filed Two particles having equal mass and charge
are separated by a distance The force(s) they
experience is (are) Statement-I: No 2 electric lines of force can intersect each other
Statement-II: tangent at any point of electric line of force gives the direction of electric field A force of is acting between two charges in air if the space between them is completely filled with glass , then the new force will be …… An electron is placed at centre of a conducting sphere of radius 0.2 metre having charge coulomb. The force of on the electron is ________ N
