Suppose charge on a metallic sphere is If the sphere
is put in contact with an identical uncharged sphere,
the charge will spread over the two spheres. By
symmetry charge on each sphere will be ……
When distance between two charged spheres is varied
so that it becomes half the initial distance, force
between them will become ……
is put in contact with an identical uncharged sphere,
the charge will spread over the two spheres. By
symmetry charge on each sphere will be ……
When distance between two charged spheres is varied
so that it becomes half the initial distance, force
between them will become ……
View answer and explanation
Correct option: B
four times
Option B is correct because when two identical spheres are in contact, the charge is equally distributed, and the force is inversely proportional to the square of the distance.

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
