Assetrion: Electric lines of force never cross each other.
Reason: Electric field at a point superimpose to give one resultant electric field

Options

A. If both assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both assertion and reason are true but Reason is not the correct explanation of the Assertion.
C. If Assertion is true, but the Reason is false.
D. If both assertion and reason are false

Answer

a

Explanation

Electric field lines of force can never intersect each other, because if they do so then at the point of intersection two tangent can be drawn which would mean two directions of force at that point which is impossible.
If there are `n` point charges `q_(1),q_(2).....q_(n)` then each of them will produce the same intensity at any point which it would have produced in the absence of other point charges, Hence, intensity of `vec(E )` is resultant of
`vec(E )_(1),vec(E )_(2).....vec(E )_(n)` as `vec(E )_(1)+vec(E)_(2)+.....+vec(E )_(n)`
