Assertion: The property that the force with which two charges attract or repel each other are not affected by the presence of a third charge.
Reason: Force on any charge due to a number of other charge is the vector sum of all the forces on that charge due to other charges, taken one at a time.
Reason: Force on any charge due to a number of other charge is the vector sum of all the forces on that charge due to other charges, taken one at a time.
View answer and explanation
Correct option: B
If both Assertion and Reason are correct, but
Reason is not the correct explanation of
Assertion
Reason is not the correct explanation of
Assertion
Option B (If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion) is correct because the superposition principle explains the net force, but doesn't directly explain why individual forces are unaffected by other charges.

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
