A positively charged rod is brought near to a nonconducting object. The rod is attracted to the object. From this observation we can't predict whether the object is charged or uncharged. Some additional experiments have been performed to identify whether the object is charged or uncharged, these experiments with their observations and conclusions drawn are given. Select the option in which conclusion drawn is correct.
View answer and explanation
Correct option: D
All of the above
Option D (All of the above) is correct because each scenario provides a valid conclusion based on the principles of electrostatic attraction and repulsion.

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
