Statement-1: In the frame of reference where all considered charges are rest, the force experienced by a moving test charge due to all considered charges are purely electrical.
Statement-2: A stationary charge produces electric field only.
Statement-2: A stationary charge produces electric field only.
View answer and explanation
Correct option: A
Statement-1 is true, Statement-2 is true, Statement-2 is the correct explanation for Statement-1
Option A is correct because Statement-1 and Statement-2 are true, and Statement-2 correctly explains why Statement-1 is true. A stationary charge only produces an electric field, and in a frame where all charges are at rest, only electric forces are present.

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

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
