Can we give any amount of charge to a capacitor?
A capacitor is connected to a battery. If we move its plates further apart, work will be done against the electrostatic attraction between the plates. What will be the effect on the energy of the capacitor?
two identical metallic spheres A and B of exactly equal masses are taken. Sphere A is given positive charge of Q coulomb and B is given an equal negative charge.So initially before the charge is given
What will be the masses after the charging?
(a) $M_A > M_B$
(b) $M_A < M_B$
(d) Nothing can be said
Statement I: A small metallic sphere is placed at the center of a large charged spherical shell and two are the connected by a wire. The charge will not flow from outer sphere to inner sphere
Statement II: A charged conductor is placed inside the hollow conductor and two are connected by the wire. The whole charge will flow on the outer surface of the outer conductor
(a) Both the statement I and II are correct
(b) Statement I is correct only
(c) Statement II is correct only
(d) Both the statement is true

(b) Electric Flux through surface A1
is not zero
(c) Electric field at the surface A2
is not zero
(d) None of these
Two conducting charged spheres X and Y having unequal charges are connected by the wire. Which of the following is true?
(a) Charge is conserved
(b) Electrostatic energy is conserved

What is true of equipotential surface?
(a) The PD between any two points on the surface is zero
(b) The electric field is always perpendicular to the surface

Electric field inside a dielectric decreases when it is placed in an external field. Give reason to support this statement.
Electric field lines can not be discontinuous. Give reason.
Why do electric field lines can never cross each other?
