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

Question

Q. Assertion:

\to τ = \to r \times \to F b u t \to τ \neq \to F \times \to r .

Reason: Cross product of a vector is commutative.

Answer 1

Electric lines of force never cross each other. Electric field at a point add up vectorally to give one resultant electric field. So, they do not have independent existence at the point of superposition so, electric lines of force do not cross each other(crossing of electric lines of force at a point means at a point two fields are having independent existence).

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