Charge, Electrostatics

STATEMENT-1 : Inside an isolated hollow spherical shell of charge, electrostatic potential is constant everywhere and STATEMENT-2 : Electric field inside a hollow spherical shell of charge is always zero.

A charge Q is kept at the centre of a conducting sphere of inner radius R_(1) and outer radius R_(2) . A point charge q is kept at a distance r(gt R_(2)) from the centre. If q experiences an electrostatic force 10 N then assuming that no other charges are present, electrostatic force experienced by Q will be :

Two metallic spheres of radii a and b are placed faraway from each other and are connected for a thin conducting wire. A charge Q is given to one of the spheres . Calculate the charge on each sphere at electrostatic equilibrium.

The crystal field theory assumes interaction between metal ion and the ligands as a purely electrostatic and ligands are supposed to be point charges. Q. Which of the following match are incorrect?

The electrostatic potential on the surface of a charged concducting sphere is 100 V . Two statements are made in this regard S_(1) : at any inside the sphere, electric intensity is zero. S_(2) : at any point inside the sphere, the electrostatic potential is 100 V .

The electrostatic potential on the surface of a charged concducting sphere is 100 V . Two statements are made in this regard S_(1) : at any inside the sphere, electric intensity is zero. S_(2) : at any point inside the sphere, the electrostatic potential is 100 V .

STATEMENT-1 : A stationary electric charge produce electrostatic field and this field exterts electrostatic force on other charge. STATEMENT-2 : Theoritically electric field is found upto infinite distance from a point charge. STATEMENT-3 : An electron is a point charge.
