Solution to numerical problem from Nootan ISC Physics of chapter 1: Electrostatics and electric fields.

Electric Charges and Fields Electric charges; conservation and quantisation of charge, Coulomb's law; superposition principle and continuous charge distribution.
Electric field, electric field due to a point charge, electric field lines, electric dipole,
electric field due to a dipole, torque on a dipole in uniform electric field. S.I. unit of charge; permittivity of free space and of dielectric medium. Frictional electricity, electric charges (two types); repulsion and attraction; simple atomic structure, electrons and ions; conductors and insulators; quantization and conservation of electric charge; Coulomb's law in vector form; Comparison with Newton’s law of gravitation; Superposition principle. Concept of electric field and its intensity; examples of different fields; gravitational, electric and magnetic; Electric field due to a point charge and group of charges. Electric dipole and dipole moment; derivation of the Electric field at a point, (1) on the axis (end on position) (2) on the perpendicular bisector (equatorial i.e. broad side on position) of a dipole, also for short dipole; dipole in a uniform electric field; net force zero, torque on an electric dipole: a point charge q in an uniform electric field experiences an electric
force. Electric lines of force: A convenient way to visualize the electric field; properties of lines of force; examples of the lines of force due to an isolated point charge, an electric dipole, two similar charges at a small distance; and uniform field between two oppositely charged parallel plates.
