A tennis ball which has been covered with charges is suspended by a thread so that it hangs between two metal plates. One plate is earthed, while other is attracted to a high voltage generator. The ball
View answer and explanation
Correct option: A
swings backward & forward hitting each plate in turn
Option A is correct because the charged ball will be attracted to the high voltage plate, then repelled after contact, and attracted to the earthed plate, then repelled, causing it to swing back and forth.

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
