Suppose a rod is given a negative charge by
rubbing it with wool. Which one of the
following statements is correct in this case?
rubbing it with wool. Which one of the
following statements is correct in this case?
View answer and explanation
Correct option: D
The negative charges are transferred from
wool to rod
wool to rod
Option D is correct. When a rod is negatively charged by rubbing with wool, negative charges (electrons) are transferred from the wool to the rod.

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
